I'm not sure why it's unreasonable?

If you have a custom mode of operation, then you'll need a custom
phy_mode as well, and surely you can have a custom set of parameters.

Since those functions are meant to provide a two-way negotiation of
the various parameters, you'll have to have that structure shared
between the two either way, so the only thing required in addition to
what you would have passing a void is one line to add that structure
in the union.

That's barely unreasonable.
