I don't think I remotely implied that the actual tags were at question
in this case.

Well that is a -slight- simplification of what happened. We can
partially follow it here
Except that we don't even know why in the end the changes were reverted,
insight? External pressure? Or what? Obviously it wasn't just people
complaining or else it would have been far earlier.
> Anyway, good luck with tagging. When you frame the discussion this way, don’t be surprised when we are reluctant to participate.
If there was more upfront transparency and discussion then likely the
whole thing likely wouldn't be needed. I'm not saying there wouldn't be
any disagreement, but it would be centred around the actual changes and
not around your behaviour which is what in the end is causing the high
