3a) add such dependency to SIGGEN_EXCLUDERECIPES_ABISAFE if it's
completely ABI safe (recipes depending on it shouldn't get rebuild after
any changes to it)
3b) add such dependency to SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS to exclude it
only for given recipe (in this case by saying that polkit-groups doesn't
need rebuild when polkit recipe is changed in any way)

I think in this case 3a) and 3b) don't apply as well, so easiest and
safest option is 2), package feeds should survive that, because new
package will have higher version (when PRserv is used) and also higher
package arch priority (all is lowest). Even the sysroot should now
survive ok, with new functionality which "uninstalls" staged file for
unreachable stamps.

Also polkit-groups build doesn't take very long, so we don't mind to
build it once per TUNE_PKGARCH instead of building it as allarch only
once but with unsafe deps.
