I've opened 1-2 dozen ports - except 80 sand 443 at 2 relays.
So I do not have the Exit flag.
Nevertheless I see about 100 exit connections at 2 relays here and do
wonder now if opening those ports is ok and which types of clients use
them ?

Here're the data of one of the relays got with [1]

ORport 9051
  0.4.7.0-alpha-dev   uptime: 7-19:57:56   flags: Fast, Guard, HSDir,
Running, Stable, V2Dir, Valid
