Like I said: good-faith mistakes do happen, but they happen rarely.
The cases you mentioned don't change and don't contradict that, even
if one agrees 100% with your assessment of what happened in those
cases.

Bad example.  The line-number display was a feature I implemented
because others requested it; I myself don't use it and consider it
un-Emacsy, as I told back then.  So I needed the feedback very much
because I couldn't myself make decisions about a feature I don't and
won't use.

If you want a better example, compare with development of
bidirectional editing support.  There, I posted a very small number of
messages describing my design decisions, but never asked for their
approval -- because in that area I know more than most anyone here.

For a smaller and more recent example, consider the implementation of
TTY menus.  Or even the recent support for thumbnails on MS-Windows.

As I made it abundantly clear, I disagree.

If you had explained what you are about to do, I would have objected
right there and then.  Instead, I was surprised to discover this the
hard way when I installed the 2nd pretest of Emacs 30 (I have no idea
how I missed that with the first pretest).

And I regret your decision very much.  I think and hope our common
goal of developing Emacs should allow us to cooperate even with people
with whom we occasionally disagree, even when the disagreements are
radical.
