systemd comparison with GNOME 3 is slightly unfair

Re password stealing, yes that's a massive concern. If a WM lets random apps paint over arbitrary windows - other than perhaps children - and steal focus without user-acknowledgement, that doesn't seem a sensible WM. Old school WMs used to require that the user explicitly place new windows with a click - which avoided the problem of focus being stolen unawares. So it's perhaps not right to say FFS is a security risk of itself, and it seems more a problem of WM window placement policy and/or how/when new windows are given focus that should be addressed, and probably regardless of focus policy. (However, this is far from my area of expertise ;) ).

Re the panel bar, if that's a temporarily missing feature, does that seem like good release engineering to you? We've seen since this "Ah, but that will be added back later" intent before, e.g. GDM and the configuration tool for it, but I bet there are more examples. It turns out that intentions don't always result in code.

OTOH, if it's a deliberate design decision then I remain confused at how GNOME 3 aims for consistence while effectively encouraging massive code divergence amongst its users!
