My Intel Wireless "self-managed" into remote regdomain, how to enforce safe defaults?

Syslog contains about 10 of these lines per day on a Laptop, using WiFi hotspot from smartphone:

wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=COUNTRY alpha2=UA
wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=COUNTRY alpha2=RU
wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=WORLD
wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=COUNTRY alpha2=US
wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=WORLD
wpa_supplicant[]: wlp59s0: CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=COUNTRY alpha2=US

• Should I worry about the device polluting unlicensed frequencies? (correct regdom: DE)
• If so, can I force the card/driver/system go back to safe default?

Notable difference to existing question:

• regardless of regulatory logged, connectivity is satisfactory
• unlike others, the card does not reset to (one) vendor default, but multiple different

Diagnostics have been collected after attempting to work around using REGDOMAIN=DE and ieee80211_regdom=DE - with no observable difference:

# grep ^[^#] /etc/default/crda
REGDOMAIN=DE

# grep cfg80211 /etc/modprobe/local.conf

Update: The wireless-regdb 2021.08.28-0ubuntu1~20.04.1 upgrade coincided with a change to logged lines with init=DRIVER type=COUNTRY alpha2=FR (still incorrect, but different).
