Q on prefixes

I mean those related to ACL (?) admin_, user_ etc…

I read in a couple of places that they are used for security. But what I have in hand is the following:

I have several users = domains all starting with same. Say transxxx.com, transyyy.com, etc and related users are transxxx, transyyy etc. I can see that on Linux level all are created distinctly, that’s fine.

But at CP level all have “tran_” prefix. If I login to phpMyAdmin as admin user, databases of these are collected under “tran”, just visual, no problem…

Are there any other implications?
