No, they're tied to the release.  Often most packages will work, but
not all, and not always.  The point of keeping package sets for the
releases are because they've undergone QA during the release, and
users know they'll always work.  Note that the release trees are
static, so they're a once-only download.

In theory, you can always prioritise your updates so that e.g. i386 is
always synced when it changes, but ia64 is not synced more than once a
month.  I don't know how easy this would be to do automatically on the
mirror end, or if more infrastructure support would be needed, but
that's out of my area.
