I would prefer to release often than creating additional snapshots.

The first release is always a heavier process because the process has
to be established.

I hope next releases would be lighter.

Sure.

Changeset ids and tags are for that: identifying a state of the sources.

Branches aren't for that, because they are lines.

I agree. Re-labeling shouldn't be allowed.

For FreeBSD, I'd like to see this issue fixed, but I don't really know
how to help.
