Indeed, a very great deal of code running on servers is in Python or Ruby. That's the low-hanging fruit before you start talking about GC overhead in a compiled language. But of course most of that is somebody else's code. People tend to be interested in what it costs to run their own code, not the next office over's.

If you believe your own argument, it would be foolish to start a rewrite while easy GC optimizations still await. Not everyone chooses wisely every time, but it's the charitable assumption.
