But we want to hide that this is an implementation detail from the
user. Having a new module just for this attribute might seem like
overkill, but I hope that we could use it for more things in the
future. Besides, if _sys is a builtin module, importing it will not
add much overhead.

I forgot to ask before: Does this deprecate platform.python_implementation()?
