I am a former Mozilla Corporation employee, so I am more willing to criticize the current state of MoCo culture as a whole...

I would say it really depends on the nature of the patches being contributed; if they are not inconsistent with project goals and not excessively burdensome, I'd hope that they in theory would be considered.

However, I will say that MoCo culture was already much different by the late 2010s than it was in the early 2010s. When I joined MoCo in 2012, there were multiple managers I interacted with who openly valued community interaction and encouraged their reports to set quarterly goals relating to mentoring external contributors. IMHO that encouragement had died off by the late 2010s.
