I have a 2016 15" fully loaded, no issues (yet). Hasn't been rebooted since the 10.13.2 patch.

I can attest to this being true on my 2017 15" rMBP (Fully Loaded). I've had at least 5 unwanted reboots a day since 10.13.2 was released. This can happen with the machine just sitting idle or while being used heavily. Workload is not a factor in when it does it.

The crash log shows a CPU trace as being the error. I'd imagine that something will be done by Apple within 10.3.3

Your computer is most likely having some other problem. Certainly, reboots are not widespread in Macs and I would not attribute 5 a day to this security update. If your kernel panics are being logged, perhaps posting one here might be useful.

Have you run Etrecheck to see if you have any daemons etc incompatible?

That said, whether anything "will be done by Apple" depends on when/whether <Intel> resolve any issues.
 
Intel released microcode patches for the individual chips. Has Apple pushed those microcode patches through to our computers?

10.13.2 was stated by Apple to contain the Spectre fixes they had, my point is that any further fixes for any rebooting issues caused by that patch(es) will probably also need to come from Intel, not Apple.

In the Pc world, I was getting the impression that Intel released patches which had a possibility of bricking systems. Since these patches were released very recently, I was guessing that they would have come out after the 10.13.2 supplemental update. Has Apple used a silent update to push a microcode patch?

Any similar native apps like this?

InSpectre's more technically inclined users have asked for more information about how InSpectre makes its decisions. Non-Windows users have also asked for that information so that InSpectre could be run on Linux and MacOS machines (under WINE) to check the non-Windows machine's CPU support. As shown to the right, InSpectre release #3 adds a “Show Technical Details” item in the system control menu at the upper-left corner of the app. Click on the little “Spectre” icon and select the “Show Tech Details” item to display the raw data obtained by InSpectre's analysis of its operating environment.

My wife has a haswell 13" MacBook Pro. I'm curious how much of a performance hit it will take when the firmware updates are released. It's my understanding it could be substantial.
