Comment (by ncohen):
> My point is that it is worth doing the forensic work to find out whether
the '''original default''' (if such it was) had a ''reason''!
The fact that this information may not have ever appeared on a public
forum is a sufficient reason to not require of a ticket's author to
produce it: otherwise every non-explained design decision becomes
impossible to fix.
I don't think you should be allowed to revert `positive_review` status
because of such a request. If you find it, however, and if the reason you
find there is compelling, then of course that would not be a problem as it
reopens the discussion.
> Especially if it can be done by emailing a few people. Rather than just
up and deciding.
You are overlooking that this patch was reviewed by a free man. I'm not
being overly authoritative here.
> You can say all you want that people will not really care because they
can easily switch, but tell that to someone doing a presentation who all
at once is befuddled because the default has changed and they are sitting
in front of 20 people who really want to know what that matrix represents
and the speaker has no clue any more...
My hope is that they will stop wondering what the former output means, and
that the new one will be more natural. It is declared to be 'more natural'
by 100% of the people I asked in my lab (without telling them which was my
choice).
> (Compare to how matplotlib is giving huge warning to their default
change in colormap. Not that this issue is anywhere near as important to
Sage as that is to them, but it still is good practice, which we are very
bad at following.)
What do you propose to give a warning? I don't see any way, but if you see
an efficient way to warn people please explain it.
