I see lots of false assertions here. Here's a significant one:

The calling conventions was marked as undefined as a first step to changing it [1]. The change was introduced by the very author of this post.

Also, a more agressive inlining mitigates the slow calling conventions.

More generally, I think it is a huge achievement for a PL to be self hosting. It makes its development easier as there is only one language to deeply know (plus assembly of course).
