Indeed, I just had to port some code that had been running happily for years at the south pole to py3 (due to EL8 upgrade and not wanting to install the py2 world). It was something talking to a HV supply over a serial port which of course only spits out bytes, but then needed to parse using string handling. It wasn't that hard to port but it took a few tries to find all the places necessary, requiring debugging over a rather slow ssh connection (that is only up when the satellite is up).
