Yeah, and it sounds strictly better that the trouble is handled by people
who maintain Python code who presumably more about Python than a random
WebKit contributor who may not know how to setup virtual environment in
Python, etc...

Again, the argument that the difficulty can be overcome and it's a minor
inconvenience isn't convincing. I can, for example, suggest that we should
just build WebKit using the latest version of clang. Anyone who uses a
system that doesn't come with the latest release of clang should just build
clang instead. There is a significant cost in having to support MSVC and
GC++ so we should just use clang everywhere and only the latest version
like Chromium does.

Each team & person has a different preference & perspective when it comes
to tooling. Please don't break someone else's working workflow based on
your preference.
