Should keep a note saying for outdoor only usage, the limit is 4000 mW.

For outdoor only usage, the limit is 1000 mW.

Also, for outdoor usage, TPC is required, and there is no provision
for 3 dB power reduction if TPC is not implemented.

So I would mark this band as indoor only for now.

There are NO-INDOOR and NO-OUTDOOR flags for the database. The kernel
doesn't have a matching IEEE80211_CHAN_OUTDOOR_ONLY flag though.
Maybe that should be added?

Johannes, what do you think?

This band is point to point only. TPC is required without provision for no TPC.

Please use "Reported-by" instead, and also add
