Well, I could use an actual justification for why I would need it.
Because, frankly, I haven't sat down and thought: "hmm, this boot
command line supplement thing is awful and I need a better one." IOW,
it has never bothered me so far. But I'm always open to improvements as
long as they don't make it worse. :)

We - SUSE - always reevaluate our configs for the next service pack and
enable things which make sense and customers use. So all the new drivers
get enabled, kernel infra which makes sense too, etc.

If the bootconfig thing proves useful, I will glady enable it in our
tree.

Not afraid - I don't know why I need it. Everything I don't need =>
off. But again, if there's a good use case, I will enable it. The usual
feature evaluation thing we all do.

Thx.
