listp is ok here, I think.  Anyway, since in most cases
"safe-local-variable" amounts to "matches type defined by customize"
anyway, why don't we just add something like an explicit ":safe" tag
to our customization types?  This could cover part or all of the
customization type, and so everything not matching the "safe" parts of
a customization pattern (including not matching the customize type at
all) would be considered unsafe.

Since the "safe" tag would be a visible part of the customization
type, the likelihood of introducing eval-capable extensions without
thinking about security implications would likely be less than what we
have now.
