That stops the moment something could use a USE- or slot operator dependency 
(because of a tree-wide change that also affects the old package). Then the 
EAPI bump suddenly becomes urgent (and a minor QA-like commit becomes a major 

And no bugs probably just means no users that could file bugs. We really need 
something like gentoostats...

Not really. It's an asymptotic curve. *If* you want to have it gone 
*completely* at some point, you have to start actively working on that. The 
only question is when, earlier or later... 

I'd guess having an EAPI approach <~ 1% of the tree is probably as good as any 
other criterion.

[[What is interesting but offtopic is that the exponential decay is the same 
for a long timeframe, see [*] third panel... the downward slope of the white 
line for EAPI=0 barely changes, and the other EAPI run parallel to it as long 
as nothing special happens... This means that Gentoo isn't dying after all, 
since the same developer activity takes place!]]
