Eli's point about ELF is a pretty strong objection to that idea.

Also, looking down the road, the GnuTLS folks seem like they don't want to let 
Emacs be in charge of memory allocation; they want to use talloc, which as far 
as I know is not compatible with Emacs memory allocation.  This sounds like it 
could be a problem.

I guess I'm not fully understanding the problem they're trying to fix.  What if 
we required that gnutls_global_set_mem_functions be called only when 
gnutls_global_initialized is zero?  Wouldn't this requirement fix the problem? 
Emacs could live with that.
