How have you tested? What results have you obtained? If you want
convince someone else you should provide testing procedures and
numeric results.

I think that no one here is  interested to determine how much the
PREEMPT_RT patch is "hard" or "soft". We are working on a kernel that
better fits our users needs.

In any case the -rt/-realtime kernel maintainer role is vacant. Are
you interested?
