You're talking out of ignorance, keep it down. Guile-Emacs runs Elisp, not Scheme, and Elisp will remain the main Emacs language for a long time. Using Scheme will become a possibility and you can bet on some people starting it immediately, but nobody is forced. Guilifying Emacs is not "pushed by the Guile guys," it's always been RMS's desire. The "Emacs guys" is a rather large group of people, which is essentially a superset of "Guile guys." Some of them would love Scheme, others wish it was CL instead, others want to take Elisp on its own path to evolution. Guile offers an evolved Elisp, and Scheme as an addition. And of course One Day someone might sit down and implement CL for Guile too, you never know. GCC, GDB, GNU Make, and some other tools can be extended in Guile. The Nix-derived package manager Guix which forms the core of the upcoming official GNU distribution is also written in Guile. It's becoming quite "relevant" on its own terms. But sure, Emacs would be a huge boost. They're both GNU software so it's a logical come-together if you ask me.
