Tramp behaves like with local lock files. Imagine, you have a local file
~/test with a lock file (a symbolic link) ~/.#test -> something. Set
create-lock-files to nil. Start editing the local file ~/test, and save
it. The local lock file ~/.#test is removed.
And that's also what's documented, see (info "(elisp) File Locks")
--8<---------------cut here---------------start------------->8---
-- User Option: remote-file-name-inhibit-locks
You can prevent the creation of remote lock files by setting the
variable ‘remote-file-name-inhibit-locks’ to ‘t’.
--8<---------------cut here---------------end--------------->8---
It speaks only about creation of remote lock files, and not about
removal. One possible workaround for you would be to eval the following
form, additionally to your settings:
--8<---------------cut here---------------start------------->8---
(fset #'tramp-handle-unlock-file #'ignore)
--8<---------------cut here---------------end--------------->8---
Best regards, Michael.
