ok, But I will cherish it in my memory so whenever the use case

re "detached HEAD is just fine" -- I guess "it depends"...  E.g.  why
should it get detached if it was not detached to start with?  Why not
just to perform a regular "git merge --recurse-submodules" within
the submodule thus making it all consistent across?

If there is a need in detached HEADs handling of merges etc, get
them detached and then they would stay detached - no surprises.

it better be ;)

That is correct

yeap - that would be beautiful.  Now I just need to do that all manually
;)

sorry I was not clear... I will start a new thread for a complete
