Upstream waf still ships with the default interpreter being "python", though the script works with both Python 2 and Python 3 (they're not changing the default choice during 2.0.x releases for compatibility reasons apparently). Add code to bootstrap.py to change the interpreter from "python" to "python3" when downloading the "waf" file. Running any mpv code under Python 2 should be considered unsupported in the future (and any code added need not work under Python 2).
