portlint: OK (looks fine.)
testport: OK (poudriere: 10amd64, 11amd64 and 12amd64)
maketest: OK (1821 passed, 32 skipped, 5 xfailed, 3 warnings in 37.97 seconds)
Note that some tests fail with the version of www/py-multidict currently in the ports tree. I'll submit an update for that port in a minute and depend this on it. The functionality of www/py-aiohttp is unaffected by this.
I only did a run-test with threema-msgapi but the successful 'make test' results suggests everything works as expected.
