If an Mx 12" MacBook was to come to pass; Apple Silicon tends to level the field unless you have specific needs. Even the M1's are still very capable in comparison to many others.
When the 12" rMB was released Apple turned everything on it's head with the performance profile & pricing excluding the majority. A 12" Mx would be perfect for the business traveller, students, the casual couch surfer and a multitude more where size & weight is a significant factor.
Predominately the Air works for all the above with ease. That said close to a decade on when you pick up the 12" rMB it still feels like someting special. Still utterly nuts that a fully functional Mac can exist in this diminutive formfactor. I still use my 2015 rMB from time to time and still enjoy it. Far from perfect yet as they say nothing compares.
Back to you post would be difficult today to see where a Mx 12" would fit in, equally I hope Apple produces one, I for one would be all in. I hammered my 2015 12" rMB in professional roles across the globe, nor confined to soft jobs.
