I don't need them :-). The point was that still majority of the drivers
will have custom parsing functions. It would be nice if we could fix
that too. I do understand that using custom "pins", "functions"... is
something which is deprecated, but if core parsing functions allow
passing custom strings for above purposes, in a similar way as your
proposal, it will be easier for those drivers to migrate, I believe.
