How does that work with live-vcs ebuilds, aka -9999 ebuilds?

To date I've seen very few if any -9999-rX ebuilds, I've assumed because 
they'll be rebuilt if the sources change anyway, and with @smart-live-
rebuild upstream changes are detected and trigger rebuilds automatically.

But now we're talking gentoo level dependency changes that either don't 
match a specific upstream change or that occur *after* the upstream 
change, so there may /be/ no timely upstream update to trigger a rebuild.

Does this then mean we should be getting -9999-rX revision bumps now, for 
gentoo level dependency changes?

If so, gentoo/kde's overlay... and I since I run live-git of nearly 
everything kde here... are in for quite some hundreds-of-packages-at-once 
fun when those eclass dep-bumps occur...

(Tho it can't be /that/ bad, since I've been running with --dynamic-deps=n 
for years now, and without --changed-deps for I'd guess a year or so 
now.  And upstream does mass version and dep bumps regularly already, 
triggering the mass rebuilds even if that's the only commit, so I suppose 
another triggered rebuild when gentoo/kde revbumps after dep-bumping to 
reflect what upstream already did, won't be /that/ much different or 
/that/ much more work.  Only now I guess I'll be seeing it in -9999-rX 
revbumps, too.)
