The users yes but their preferences and properties not, right? Whatever is needed to make Special:Contributions etc. work correctly.

Special:Contributions and Special:Log work fine if the user ids in the revision and log tables are set to 0 and the user names don't exist in the user table.

You can't mix and match that, though - if the user ids in the revision or log tables are 0 and the user names do exist in the user table, that's when you get problems.

Or visa versa.

But if you don't need users to be able to log in, you might as well just set all of the user ids in the other tables to 0.
