AFAIK it's still widely used, and supported by third parties. And even
if not it's not that the python usage in perf needs any external support.

In Linux deprecation is generally tied to nobody using something
anymore, and that is clearly not the case here.

That's code that practically never changes, so I don't see any
maintenance benefit. I mean it needs to be compile tested / perf tested, 
but Arnaldo's container collection will do that practically
for free.
