Personally, I feel a bit like doing nothing at the moment might
be the best solution. If BESPOKE is for icky stuff that won't be
generic trying to pull out generic fields to go in snd_enc_generic
seems like a challenging exercise, and we can look submissions
that use it and keep an eye out for anything that might be
generic enough to go in there, rather than adding a bunch of
stuff that ends up never getting used.

Thanks,
