OK, great.

Of course. It's not a trivial change, but it's also a much smaller scope feature than say switching your deeply ingrained software licensing system or adding 3D audio support, so this has to be mainly a question of prioritization. (I've spent a lot of time writing MIDI software and dealing with the annoying differences across audio plugin APIs, so I'm very familiar with this particular problem set -- as I know you are too).

DDMF MetaPlugin, DDMF SuperPlugin, Kushview Element, PlogueBidule, perhaps even KompleteKontrol, are all possible plugins which come in VST2 form and can host VST3 plugins inside of themselves..which will essentially allow you to use K7 inside VePro7 right now.
I have a few of these -- I guess I'm just hesitant to add yet another layer of nesting (DAW => VEP => Wrapper Host => Actual Sample Player). Has to add at least a small bit of memory + CPU processing overhead, adds additional clicks to the already arduous process of large orchestral template building, puts critical reliance on another manufacturer+software staying up to date with OS compatibility issues, etc.

The VST3 spec also has some interesting design problems that can sometimes affect midi in problematic ways that does not exist with VST2, so me personally I always choose VST2 whenever possible and I will continue to do that as long as I can until it truly becomes a situation such that for example, there may be some sample library that only works on K7 which is only VST3... But we're just not there yet, there are really only a few isolated situations where VST3 is a hard requirement.
It's not a hard requirement right now, but there will come a point in the not too distant future where it is, so before investing tens/hundreds more hours building new large templates, I'd rather future proof as much of that work as possible. I do save sample player specific preset files, of course, but even just the work of having to load a new plugin format and call up each one of those presets across dozens of libraries is going to be mind numbing.
So I'd prefer to start using VST3 plugins in VEP as soon as possible, even when that means having to deal with annoyances like choosing keyswitches instead of MIDI CCs for more reliable articulation management because of those VST3 design quirks.
