I'd guess the URL form remains as Jacque described, a whole-file
operation. It only takes a couple extra lines to do the
open/write/close alternative, and in the minority of cases in which we
need fine-grained control over file I/O it's no more onerous than the
only file I/O syntax the root tongue, HyperTalk, offered.
It'd be nice to have, but the team has a long list ahead of them, and
relatively few engine contributions from the community to fill in the
gaps on these nice-to-haves.
I'm just grateful we have the various "open file" modes at all - being
able to use "update" and "append" are godsends for a wide range of tasks
involving large files.
Even better, Mark Waddingham updated the file I/O stuff a few versions
back so that it can accept >32-bit values for the length in the file
spec, allowing us to traverse files > 4 GB. It's not often I have to do
that, but I discovered the older limitation when I was given a 6.2 GB
file to slice and dice and now I can do so with ease, using "seek" to
jump around in the file to get the parts I need.

Your find prompted me to do a search in the bug DB for all reports that
include "sc...@runrev.com" among the commenters and found some other
gems from the olden days, like this useful tidbit I never knew before
(is this documented?):
...you can use numbers of the form "0xFFFFFFFF" directly
in scripts, saving you the rigamarole of using numToChar
to build them up...
