I think it would help if we moved it to something like
"internal/pg_xlog" and "internal/pg_clog".  Keep the name but move it
out of sight.

We have a tool called pg_xlogdump in the standard installation.  initdb
has an option --xlogdir, pg_basebackup has --xlog and others.  Renaming
the xlog directory would make this all a bit confusing, unless we're
prepared to rename the programs and options as well.
