Hi Junio,

Thanks for the detailed reply. That makes sense, and it's useful to
know that the approach is technically viable.

I'm afraid I'm not sufficiently familiar with Git's internals to take
this on myself, but hopefully someone with more experience in that
area might be interested in implementing it.

I've seen lots of complaints about Solid State Drives dying due to
worktree use. I personally have a repo containing over 80GB of images
that never change, so currently worktrees just aren't an option for
me. I hope this will change in the near future!
