It isn't clear to me exactly what you're suggesting.  Are you suggesting
that we allow "head" instead of "HEAD" in worktrees, or that we allow
refs in general to be case insensitive, or something else?

There is a proposal for a ref storage backend called "reftable" which
will not store the ref names in the file system, and work is being done
on it.  There has been a suggestion for an SQLite store in the past, but
that causes problems for certain implementations, such as JGit, which do
not want to have C bindings.
