I don't think it's that easy ... updates that are in progress are still
likely to see issues.  For instance, the package list you pulled ten
minutes ago might say foo-1.2.3 is current, but by now the one that's
visible on http is foo-1.2.4.  This is presumably soluble (eg, maybe
keep recently-obsoleted packages on-line for awhile), but it's certainly
not as simple as swapping a top-level symlink.
