[x] Empty or non-existing project or focus-area silences warning. Maybe special case some "non-project" focus areas (ssc) to avoid listing it? Maybe list non-existing projects / focus-areas? Should require (valid) focus-area, probably.
[x] Should have a standard "Virtual" location suggestion.
[ ] Team group by area, maybe filters by affiliated or mainly supported, etc.
[ ] Document "core". Maybe error if any other focus area found? ✅
[x] Can we remove the reliance on short names? Or automate them? They are a problem when the filename doesn't match the short name in some cases. (not removed, but forced to match)
Maybe a discussions page would be better?
