Recent versions of sliderotate do not conflict with osso-software-version-rx?4-unlocked; in any event uninstalling sliderotate would not restore that... Some early rotation packages did force removing an osso-software-version, but I think since the first SSU they've been largely ok.

Removing osso-software-version-rx?4-unlocked is an additional cause, however it happens, and can (AFAIK) only really be fixed ahead of time by installing it again.
