> How is hwsim related to ETSI? What does it matter?

It's well known that the frequency bands 2,4 GHz and 5 GHz are mainly
used by Radio LANs and in many cases, the deployed technology is based
on the IEEE 802.11 standards family. However, other technologies such
as LTE-LAA are deployed in those frequency bands as well. That said,
considering that hwsim is an excellent module that can be used in
different network simulation scenarios; that it is not only used in
North America; and also considering that some regulatory power limits
are taken from the ETSI standards, why not set a maximum value
supported by a renowned Institute? Without this new value, regdomain
will not work as expected for some countries.
