Yes, overwrite and import te product XML is the standard procedure to update hacks.

Do you also prefer to manually remove registry entries?

Uninstall shoul clean up everything, so the board & database is in the same state as before the installation.
Anyway, this Hack could also be tagged "Final" (as there are no big issues whatsoever), so discussing about not having uninstall-codes for "pre-release versions" doesn't make much sense.

You won't see Beta 2 for a while, I just updated the laguage packs.
