>From my POV, it _is_ a good argument.  Especially when the defaults
change in a feature that is easily customizable, and so basically you
are asking to impose your preferences, which are easily catered to by
your local customizations, on everyone else.

That's not true.  We do that rarely and sparingly, precisely for the
reasons you consider unimportant.

You can do the same with the current defaults, so why are you asking
us to change them?
