I think an auto-filtering system for \l and other backslash commands as
needed, makes a lot more sense than trying
to deny access to the catalogs. Obscuring them for security reasons is no
win, really. Obscuring them so user number 1,000,000 in his own database
doesn't have to look at user numbers 1 through 999,999 to see his database
go by.
While I'm not sure I'd build a 1,000,000 user database, somewhere between
the 80 we currently have at work and a few thousand you'd go nuts if you
saw a bunch of data that didn't belong to you every time you hit \l.
