Yea, both patches are sensible.

IIRC the desire for name-rev was for detached HEAD in contexts like what git submodule produce. If you are sitting on a tagged version in a submodule, its nice to see that in your prompt. Since you aren't developing there right now, there is no branch, and you are just sightseeing.

This feature may have started at my prior job, where we had our own git submodule like tool integrated with our build system, that predated git submodule. But its also still really useful with say the Android Open Source Project, where users have 150 or so git repositories, all on detached HEADs, most pointing at an annotated tag.
