Hello,
this interesting discussion about the hybrid configuration makes me think about a similar situation with sky diving:

-Everybody opens his or her own parachute manually, looking at the altitude, (...mCCR)
-In addition each chute has a safety device that opens it automatically (actually the reserve parachute) when at a free fall speed below some low altitude threshold (...eCCR). But interestingly, it has never been used as routine (notably in training).
People are not proud when it opens: they have to replace a small rope loop, repack their reserve parachute, it shows they have crossed a limit, and it is way more stylish to open it manually.

So it looks like a mCCR mindset, with the electronics as back up.

If (when?) I had a hybrid CCR, I would look at it this way:
-a mental seal (or game) about not using the solenoid (low SP), thinking about the beauty to be all over the ppO2 with orifice+manually.
- the peace of mind of knowing the electronics are there (low chance that they fail when I happen to need them, as long as proper checking is done in a way or another at every dive)
- not thinking about any mental switch to eCCR mode explained above until I really feel a need (task loading, depth...) if any.
