If I'm reading this right, the thread from 2010-06 has 8 messages and 5
participants. There is no way it can be representative of Emacs users in
general.

I don't think that's true anymore. You should at least remember the bug
I posted relatively recently:

Like I explained in the bug above, the current behavior creates problems
in edge cases. So a users can choose the values that "work almost right,
but not exactly". Naturally, many people might be okay with that.
