Question

Is there a way to "unset" a preference variable?

One issue I have discovered is that some plugins use preferences that are "set to anything is true".

The problem with this is that once set (for example in the site-wide prefs) there is no way to return it to "undef" so it appears as False (that I can see).

(In fact, IMO, these kinds of prefs should be 0/1 boolean types - using perl's undef is bad practice since its not a concept exposed to the user)

Is there a way to do this?
