When I visit https://en.wikipedia.org/wiki/Special:Preferences?useskin=monobook#mw-prefsection-betafeatures
Compact personal bar takes up a lot of screen real estate even though I can't use it.
Why show it all?
IF we need to show it we should show it at the bottom of the page in a less prominent footer
e.g. Features available for other skins: Compact personal bar
This is needed for mobile to explore using it.
