Indeed, this would be nice to have.  Now the wrapping option was implemented
in bug#47599.

My point was that this required adding a completely new separate option,
not turning the existing hook into defcustom.

The existing hooks are intended to be used by modes,
and indeed they are used by modes that directly change the values
of these variable.  When the users will try to customize them,
this might have unintended consequences.
