There are a few options:

If the user does not require them, don't even implement them. If the
user is not using them, who is?

Implement them in an out of tree patch, which your development team
can use, since these are not user configuration options.

devlink is a possibility, but developers complain it is slow to get
them merged since we want to understand what the configuration option
does, why would i want to use it, would any other vendor have the same
need, and should it be made generic etc.

You could join those asking for fwctl, which is a contentious subject.
