TWiki::Func today, I came across permissionSet. What an odd little function!
What does it do? - it tells you if there are any permissions (VIEW, CHANGE) set on a web (i.e. in WebPreferences)
Where is it used? - Never in the core. Once, in TigerSkinPlugin
What is it useful for? - not much, AFAICT
So I propose to deprecate it, as described in Bugs:Item3578
Remember, deprecation doesn't imply removal - it just says "don't use this method". We will remove it at some distant point in the future, I'm sure. However if you feel you can't live without this function, shout and the deprecation can easily be raised.
