Well, in the meantime you can do what the PKGBUILDs do, and use
sed -i 's:\(env[ ]\+python$\|/usr/bin/python$\):\12:g'
to fix the shebangs automatically for each file needed.
You can simply apply that to all *.py files, or if some of them
specifically need python3 you can make a list of them and exclude
them/add python3 to them.
Obviously, the long-term goal should be to get that done as an upstream bugfix.
