So, “Pros” don’t want a port with 40Gb/s throughput capable of:
Nobody is saying they don't want USB-C/TB3 ports for those few devices that can actually take advantage of them. All they're asking for is a couple of good old USB-A ports - and maybe a HDMI -
as well so that they don't need to use up the (very limited number, 2 to 4) of high-speed ports for boring old peripherals that might not even need USB 3 - and so that they don't need to rummage for a dongle when they're "on the road" and somebody hands them a USB stick, or they want to use a cellular modem, or charge a USB gizmo, or...
You may notice that far fewer people are complaining about USB-C/TB3 on the Mini/iMac/iMac Pro because Apple managed to add them
without removing all of the so-called "legacy" ports.
Apple had one job to do in 2016 - take the Retina MBP design that everybody liked (including the industry-leading keyboard), update the innards and change the TB2 ports to TB3. Instead, apparently, what we wanted was something a few mm thinner (immediately offset for many people by the sudden need to carry a multiport hub and extra dongles around).
I am a media composer and have a sweet Mac mini 2018, i7 processor, six core, 32GB machine. Everything I have runs off of USB-C.
Nay, nay and thrice nay = that's impossible - because the Mac Mini retained its "legacy" USB-A, HDMI and Ethernet ports alongside TB3/USB-C, and apparently the only way for people to bask in the pure new light of the one true connector is for all of those hated legacy ports to be banished into the outer darkness and denied to all those who might find them useful.
Sorry - you've been corrupted - you may not be using those USB-A ports but they're there, tempting you, and there could come a day when you will think "Hey, that audio interface doesn't even need USB3 so why don't I just use the cable that came with it to connect it to a USB-A port and save a Thunderbolt port... what harm could it do?" and, lo, thou will have forsaken the Perfect Port, fallen from grace and shalt be excommunicated by the First Church of the Reversible SmartPlug.

NR: If it works for you, that's great - how hard is it to understand that it might not work for
other people?
(Plus, its a mini desktop so having a few dongles hanging off the back is not the issue it would be with a laptop).
