Actually this has, at least on the browser embedded editor sid,e
improved quite a bit. For example the Canton of Zürich released 10cm
nominal resolution imagery early this year and at least in iD you will
get this imagery as default now if you edit there, just as you will get
the imagery from the Canton Aargau here (which while essentially just a
service fee, we did pay CHF 200 for). While I'm not particularly happy
with just a flag to indicate the preferable imagery for a region, it
does work most of the time.
