Ideally there would be a proper solution for this kind of situations,
as of now, yes that's the “best option”. See also:

Indeed, I'll clarify the man page to mention that it's strongly
deprecated in case they can be replaced with the other --control
commands, but that there might be other cases that might still need
it, and that it will not disappear as long as there's no better ways
to accomplish those. Hope that helps.
