I don't think that's actually true; it's just not worth the effort,
and isn't an issue when you follow the Emacs conventions. (I did toy
with the idea of making it work.)

It's also rather useful during development.

Emacs memory requirements, coupled with its poor GC, are certainly
significant in the situations I typically use it. That was even a
motivation for me working on the GC. Since no one else appears to be
interested, I assume this doesn't apply to developers, but perhaps
they don't have a sufficiently wide perspective. (I'm currently in 32
MB.)
As it happens, I do occasionally unload a Gnus feature which leaks.
That typically reduces the number of used conses from ~1M to ~300k and
means GC then doesn't typically thrash on my work system though it
leaves a lot of unused ones.
