No deprecation warning at run time, just one on the man page. One thing findref remains able to do that find cannot is to run in a bare repo. Find was made to refuse to run in a bare repo because it seemed confusing for it to not list any files ever in that situation. It would be better for find --branch to work in a bare repo but not without --branch but I don't currently have a way to do that. Probably a better solution would be to make git-annex in a bare repo default to --branch master or something like that instead of --all. This commit was sponsored by Denis Dzyubenko on Patreon.
