For that to work the library would have to create an UI thread which
is always ready to respond to resize requests, and it could *not* do
the actual drawing which can be potentially time consuming.

I don't see what you get here.

Many applications will refuse to use that because they cannot accept
multi-threaded operation for some technical reason (usually imposed by
some other library) and you still don't get any guarantee about the
behaviour because the moment this library invokes any application
supplied callback it does not guarantee anything and when it does not
it cannot do anything being virtually useless.

Plus even if you provided such lib and it somehow worked it would be
useless for applications written in sane languages (eg. not C).
