The evidence suggests that, while some people undoubtedly want that
(and it's a perfectly legitimate desire), there isn't enough demand
to induce anyone to actually produce such a thing and for it to
catch on. Developers have had decades to define and implement the
kind of language you're talking about.  Why haven't they?

Perhaps many settle for using C but using a lesser C compiler or one
with optimisation turned off.

What is "lesser C compiler"?
Something like IAR ? Yes, people use it.
Something like TI? People use it when they have no other choice.
20 years ago there were Diab Data, Kiel and few others. I didn't hear
about them lately.
Microchip, I'd guess, still has its own compilers for many of their
families, but that's because they have to. "Bigger" compilers dont want
to support this chips.
On the opposite edge of scale, IBM has compilers for their mainframes
and for POWER/AIX. The former are used widely. The later are quickly
losing to "bigger' compilers running on the same platform.

 

As to tcc, mcc, lccwin etc... those only used by hobbyists.

 AFAIK lccwin can be used commercially.

"/Can/ be used commercially" does not imply "/is/ used professionally". I'm sure there are some people who use it in their work, but I would expect that in any statistics about compiler usage, it would be in the "Others < 0.1%" category.

I guess you mean companies using big tools and big ecosystems that need equally big compilers to go with them.
 I mainly use, and develop, small, nippy tools and would rate them above above any of the big, glossy ones.
 

Then you use a different rating system than the vast majority of professionals.  That, of course, is your free choice to make - just don't be surprised when others disagree with you.
