Having cmd() and command() methods in one class doesn't look good.
Rename cmd() to cmd_raw(), to show its meaning better.
We also want to rename command() to cmd() in future, so this commit is a
necessary first step.
Keep new cmd_raw() only in a few places where it's really needed and
move to command() where possible.

The commit message didn't say anything about dropping the
cmd_id parameter. Presumably you've found that it is not
used in any caller that exists, but still it feels like
a valid parameter to want to support in this method ?
Hmm, right. That should be a separate patch. Still, I think, when trying to
unify similar functions, it's good to drop first any unused thing, to produce
more clear new interface.

I'd suggest that re-writing callers to use 'command' is better
done in a prior patch, so that this patch is purely a rename of
cmd -> cmd_raw with no functional changes intermixed.
Agree, will do. Thanks for reviewing!
