If 'category where allowed to be a symbol then buffer local values could
be set.

`category' is already a symbol.  I presume you're saying, "if the user
were able to specify a custom forwarding symbol to use instead of
`category', then ..."

Sorry, I meant "to be a variable containing a symbol". Would that be any problem?

I'm not sure it's a good idea though, as in many cases overlay lookups
are implicit, so there's no easy/clean way to specify what symbol to use
(instead of `category').
