Reminder, we have this new list dim-tools at lists.freedesktop.org for
maintainer tools patches. Cc'd.

I guess I'd like more rationale here. Is this something we should be
doing? Is anyone else doing this?

This seems like an overly complicated way to achieve what you want.
Just put these under "Internal configuration." instead:
dim_gpg_sign_tag=${DIM_GPG_KEYID:+-u $DIM_GPG_KEYID}
dim_gpg_sign_commit=${DIM_GPG_KEYID:+-S$DIM_GPG_KEYID}
And use directly in git tag and commit, respectively?
Although... perhaps starting to sign tags should not force signing
commits?
