No eSATAp
I don't see the need for it, probably, neither do they
I have a Thunderbolt-eSATA hub from Lacie and it connects to RAID boxes that have their own power.
I want to plug and unplug a portable SSD twice a day.
Get a 2.5" Thunderbolt enclosure?
Maybe you want to think about to get a USB 3.0 case for your mobile ssd. Its faster than esata. If you dont have USB 3.0 ports, heck maybe use firewire 800 which is still better than USB 2.0 or think about get just a Thunderbolt case for the SSD.
Lets be honest who is using esata drives these days? Especially in the mac world.
Because the fact that Thunderbolt docks have at most only 2 Thunderbolt ports is an even bigger FAIL ?
----------
Because there would be no UNMAP currently using USB 3.0, AFAIK ?
That "fail" that all thunderbolt docks have at most 2 ports is because you dont double or tripple this bus. This isnt USB. It it ultimately a different thing. It is to daisy chain the stuff on a PCIe bus. Yes the fail is at the devices which support only 1 thunderbolt port and not 2.
You mean UNMAP in things like trim?
Well I dont know about that but everyone is using SSDs with USB 3 or thunderbolt and heard nothing bad about it.
Yes, UNMAP, like one would use over UASP, so USB 3.0 is out.
If there were a 1-bay 2.5" Thunderbolt enclosure with 2 ports, I would have already bought it.
Maybe something like this?

use the esata port from something you get from thunderbolt like a dock or thunderbolt -> esata adapter and get the power for esatap from usb
Yes its not really elegant. But I think there is not really much of a market for especially esatap so sad it sounds. I would go this far and say there is not much market for esata anyway. It sounds like you have a very special setup and there is a solution but not a pretty one
No eSATAp
Dock guys probably just implement eSATA circuits from 5 years ago, before eSATAp was implemented. They just grabbed something they used on another product and plugged it in. SATA interoperability compliance is such a pain that sometimes developers just reuse what worked before. You would think they would use current stuff, its easy to put power on the cable.... but my experience is that most overlook portable eSATA drives in their use cases.
People still use eSATA?
Most prosumers and pros do if they do a lot of hard drive stuff with or without encryption. USB3 just can't cut it with its command set limitations and protocol inefficiencies. I use eSATA as much as I can, especially for any software RAID applications.
I like this thing http://www.akitio.com/accessories/thunder-dock
Pro here. Haven't used eSATA in 4 years running a high end post production facility. All USB 3, RAID and Thunderbolt. But to each their own.

Do you know if indeed there's no UNMAP with a Mac and a UASP enclosure?
The problem lies in people not knowing what TRIM actually is. People seem to be thinking that TRIM is crucial for an ssd to work which isn't true. There is also GC and both are only used for clearing out NAND cells that aren't used any more. Having TRIM on an external SSD is just a very big bonus imo.Maybe the problem lies in that people don't know that they are lacking TRIM with USB in the general lack of awareness about eSATAp (I am thinking about a particularly shortsighted vendor to blame in part about that).
eSATA is very hard to find, normal SATA devices however...so what we're seeing are a lot of products aimed at interfacing with SATA (USB2/USB3/Thunderbolt-SATA docks). Manufacturers are getting rid of their eSATA ports; take a good look at the various models (the Dell Optiplex series is a good one: used to have eSATA, now comes without it).It would be cheap to use eSATAp connectors and just provide power to them in Thunderbolt docks, while it would be a major selling point.
