So the question is "When is it OK to merge from the trunk into release?"

I see a couple of different possible answers:

a) When the library is as good as the author can make it

b) When the library is better in at least one way than the current release
and in no way worse. That is when releasing the changes will
result in an improvement for someone and cause no harm to anyone.

c) When tests pass on "release compilers"

For a new library I would prefer a). For an improvement/bug fix to
and existing library, I would prefer b). Personally, I would never
prefer c) since it opens up a whole issue of what it means to
be "release platform" which I don't think is a very useful concept
in this context.
