Thanks I appreciate the information. The birding, wildlife, sporting, landscape R7 thread had pushed me back towards a 5dM4 due to the comments about the image issues with the R7.

What image issues? As often on these forums IMHO the "problems" are blown out of proportion. You have a fast mechanical shutter working at up to 15 fps, the shutter shock of the fully mechanical shutter (in case you are worried about that) is still smaller than the mirror slap on many if not all DSLR. For birding, wildlife you won't be using lenses faster than f/2 where the shadow of the second shutter curtain in EFCS would influence the bokeh highlights, so you can easily use EFCS without any problems. Yes, the sensor readout in fully electronic shutter is slow and limited to 12 bit A/D conversion (EFCS and mechanical shutter work with 14 bit A/D conversion). The place where the slow sensor readout becomes problematic will be the pre burst shooting (where you may lose the odd shot from the burst when parts of the subject move too fast for the sensor readout or your panning screws up the background) - but that option doesn't exist in the DSLR at all, so that is a rather moot point to revert to a previous technology because a new option isn't without limitations.

The focus stacking though I consider a useless gimmick. Focus stacks do not work for my subjects (insects and native orchids) at all, so that is a feature that may impress NOOBs

Well your entitled to your opinion even if I think a bit harsh - IMHO focus stacking can work well with orchids and insects in the field with some effort put in, such as with Helicon Soft - with images looking fine at A3 size prints free of artefacts normally with some work.

but the only lens that this could work with doesn't even have an autofocus motor (MP/E 65mm f/2.8, at 5:1 magnification ratio the subject size vs. magnification changes in a macro stack between overlapping subject areas is small enough to not completely mess up the stack)...

Now get that for extreme > 1X macro.

Semi-macro 0.5-1.0 life size and the amazing range of macros available can work just fine with focus stacking.
