I'm curious -- have you measured or heard any evidence that the process continues to occur once break-in has occurred? A lot of us are using very old Maggies and they seem to hold up until you get materials failure. By way of contrast, the true ribbon tweeters will degrade and start to "hang loose" or break if you drive them at higher than typical levels.

Dynamic speakers too have a break-in period that designers have to take into account in the design process. Again, once the driver is broken in the compliance seems to stabilize until materials failure occurs.

I'd expect large vs. small diaphragms to involve various tradeoffs, not the least of them cost: If you partitioned the midrange or tweeter on a large diaphragm you'd add to construction and wiring costs and possibly introduce some vertical response anomalies owing to the dishing of the diaphragm segments. You'd also create a dead area near every partition, reducing output for a given Xmax. On the flip side, you'd have better control of vertical resonances. The BG Neos are certainly excellent and following Satie's lead, I'll probably be using them myself as the midrange of my rebuilt Tympani IVa's.

Also, I think electrostatics are different in some respects from planar magnetics, since with their substantially lower Xmax per unit area the drivers can't be made narrow enough for good dispersion. This means that you have to curve the diaphragm as in the Martin-Logans, which has a distortion penalty; use facets to curve the diaphragm, as in the Sound Labs; use time delayed segments as in the Quad; or tolerate beaming, as in the Sanders. I saw some measurements on DIY audio from someone who spent a lot of time tuning the diaphragm segments of his home-built electrostatics to reduce resonances. Extremely impressive.
