Well, yes, but a defcustom is just a fancy variable declaration plus
an even fancier interface to setting it. Whether it makes sense for
the variable to be automatically buffer-local or not is independent of
it being a defcustom, as witnessed by the fact that there are already
automatically buffer-local defcustom'ized variables in the sources.

In other words: that customize handles poorly these kind of variables
is a bug in Customize (and so, something to fix some day), not an
intrinsic feature of these variables.
