If you need help, create sub defects and we'll get people to work on them.
Not convinced that we're ready to build without Py2 on the host. I have a branch disable hosttools for python2* but this doesn't detect recipes that end up calling /usr/bin/python directly. Will do a container thing and test.
python-native fails to build without a python on the host. It tries to use the host python3 but the script isn't py3-safe. I believe patching python2 would be relatively simple.
