OTP settings are fancier than when EWMH seems to support, so I don't
think that's a good option.
I guess we could have an additional boolean `otp_set` field which means
"OTP value was explicitly set", and if it's not set, then use
EWMH's priority. But most likely just using OTP's if it's non-zero and
EWMH's otherwise is probably good enough (i.e. ignoring EWMH's priority
if OTP's is non-zero).
