I would welcome such an effort.  It is, however, a different story
to move things simply because we want to move them, without a
concrete need or strategy to do so.

In any case, the root level of the 'lib/' directory introduced by
the 'ps/libgit-in-subdir' topic is full of source files, with only a
small number of focused subdirectories like 'odb/', 'refs/', and
'ewah/' mixed in to house specific subsystems.  This merely shifts
the clutter one level down without resolving it.

I would rather see a structure where each subsystem-like group
carves out its own directory.

I do not particularly care whether such a directory lives at the
root level or inside 'lib/'.  But if we were to establish a sensible
grouping, I suspect we would not need a 'lib/' directory solely to
house the 'refs/' and 'odb/' subdirectories.  Instead, it would be
sufficiently clean to have 'refs/', 'odb/', and other subsystem
directories directly under the root level.

I do not think we want to do this in a single large change.  If we
were to move everything to 'lib/' only to then need to further group
them into subdirectories of 'lib/', it would subject us to multiple
rounds of disruption.  I suspect it would be far less disruptive if
we migrated one subsystem at a time, directly to a new directory
immediately below the root level.
