Huh? My understanding is I have the same powers as other committers, no
more but also, no less. If you've seen me claim otherwise, please point
where that happened.

Me saying "I object" seems to attract more attention than others for some
reason. Why is it a discussion point that I object to a patch, whereas if
you do it, thats fine?

All very strange. People commit changes they didn't post all the time,
especially on minor bugs such as this.

Obviously if I knew that it would be controversial I would not have done
it. We are discussing it now, so I don't see any problem.
