I was talking about this case, were foo-2 is in testing and is not ready
for stable. It's not questionable to go directly to stable if security is
involved in the process.

Agree. The question bringing here is: how can we minimize the risk if
this situation appear, where we have an EAPI change between ebuilds in 
stable and testing branch and EAPI in testing can only be managed by
testing PMs.

Well, when I think about having to revert eapi changes or having to
make own backports and apply these solutions directly to stable because
we are using some features not supported by stable PMs, I have doubts
if it wouldn't be better to avoid these situations and wait for the PMs
to be stable.

It's not about realistic, just about how risky the solutions could be to
be in our stable branch. Perhaps I'm being very pessimistic. Leave the 
question here and we will see what happen in the future. 
We'll back to this if needed. 

Thanks.
