Locking old versions

As of now, there's no way to prevent users using older versions, except for deleting it.
I'd like to be able to lock the version, meaning no downloads nor generations.

My reasoning is that if I make a model/lora and I'm not satisfied with the results, but the post already accumulated quite a bit of downloads and uses, I basically don't want to lose those by deleting the older version.

Two options for locks:

1. Permanently locked, therefore file can be scheduled for deletion from the servers. Cleaning up some space. Notifying users that this model can no longer be used as there's updated version but post/images/likes/downloads are preserved.

2. Just settings lock (still no gens or downloads) but nothing is scheduled for deletion. As users might request from the owner/creator to unlock the model.
   

Probably need a bit more thought around this, but it might be greatly appreciated feature by users that do a lot of versioning.

Thanks!
