It'd have to be a bit more complex than that.
(insert-char ?\n (1+ (gap-size)))
worked just fine on that nearly-2GB file,
and I later typed additional randomish text without
trouble (this is on 32-bit Emacs configured --with-wide-int).

One can easily come up with the more-complex edits
that will make Emacs run out of memory editing that file,
but these problems are not unknown with a 500 MB limit as well.
Users who skate that close to memory's edge
already understand that there are limits.  It's nicer
to have the edge be at 2 GB rather than 500 MB.

I typically want just read-only access to large text
files, and support for more-complex edits isn't
so high a priority.
