Re: [PATCH 0/6] git-rm absorbs submodule git directory before deletion

I guess the latter is the case, so embedding is actually inside
the working tree and un-embedding is the relocation to the
superproject.

Another reason why I personally see a .git in each submodule working
tree is "embedded" has nothing to do with Git.  It is an analogy I
feel (perhaps it is just me) with the word "embedded reporters in
warzone".  These people are spread around, assigned to units to
report from places closer to the front line and being closer to the
leaf of the hierarchy, as opposed to be assigned to a more central
place like HQ to do their reporting.
