Actually... it's very VERY unlikely that the filename will occupy space
that's needed for other save data.  If the filename is to be stored in the
Atari's RAM, then that's X bytes of RAM you don't have for other data.

It looks like the proposed standard file size is 128 bytes.  If you store
the filename at the beginning (or end) of the Atari's RAM, then the save
function could simply iterate through and save all 128 bytes of RAM... short
and sweet.  The loader could then read only the chunk(s) it needs or even
the entire RAM state (as long as the loader itself doesn't require a RAM
counter or some such).
