Totally agree

Me too. However - I don't think this should be default behavior. The
reason is that if we make the initial outline color a non-desaturated
color (say dark blue if a polygon layer is assigned a blue fill
color), then this outline color is kept whenever a
categorized/graduated style is applied to the layer. So you'd end up
with classes with different colors (say red/green/yellow) having a
dark blue outline color. This is going to be ugly, yet a lot of users
may not notice AND even if they do it's non-trivial to change this for
new QGIS users.

So I'd rather stick with the safer option and keep the
"make-the-outline-a-darker-version-of-the-fill" as an advanced users
tweak.
