Because Emacs is written in these 2 languages.  Sorry, I thought that
was clear.

I expected those languages to be supported already, which is why I
didn't mention them.

It's too late for landing such features on emacs-26.  Sorry, it will
have to wait until Emacs 27.

Emacs 26 is nearing its release; the stream of serious bugs (or any
bugs, actually) seems to have died out.  So hopefully one more
pretest, and we will be ready to go.  Adding a significant new
feature, which will no doubt need changes in other places, is
incompatible with that.
