That sounds like a good solution, for archives with no '.' in the filename.

I guess the main problem is if the archive is huge, updating an existing
archive might (?) be more efficient than creating an entirely new one.

Another way to go about it could be to temporarily rename the archive to
have a name with a '.' in it, make the change, and then rename it back;
conceptually:

  mv a a.zip
  # update a.zip rather than a
  mv a.zip a

That has its own set of possible problems.

Maybe you could make a link to the original archive, where the link has
a '.' in the name, have zip update the file via the link and then remove
the link again; conceptually:

  ln a a.zip
  # update a.zip rather than a
  rm a.zip

I think I like this the most, but again...
