And we have a winner. The only workable solution is to get Apple to
Finder to support the OFFLINE flag. However good luck getting Apple to
actually do anything.

An alternative approach might be to somehow detect the client
connecting is running MacOS and prohibit recalls for them. However I am
not sure the Samba team would be keen on accepting such patches unless
it could be done in say VFS module.
