Read-only access to a single such file (i.e. starting a new Emacs
session for that file) is indeed not affected by fragmentation.

I'd be surprised if non-simple edits (e.g. insertion of enough text to
overflow the gap and force a reallocation) works at all.
It's also to be expected that viewing such a 2GB file will fail if
you've already viewed a 1GB file in the same session.
I.e. 2GB files will work sometimes, but e.g. for Rmail-style uses (one
of the more convincing use cases, AFAIK), I don't think 2GB is
a realistic limit.
