I agree, and tried to do this change a while ago. Unfortunately it's
not easy (possible?). Here's an example why:

If we change default outline/stroke/border to be slightly darker
version of polygon color it works nicely for single symbol renderers.
But the same changes apply also to graduated/categorised renderers.
And this means that all the classes created with the default ramp have
their outline colors set to darker versions of the class color. If you
then go and change the ramp, all the fill colors update to reflect but
not the outline color. There's no way to differentiate the slightly
darker outline color set by default from a user-set slightly darker
outline color. So we can't wipe them out and replace them all, but
this means that the outline color will be a different hue to the new
class fill color. Really ugly, and a step back from just having a
'neutral' black color...
