Is there something I can do that would help alleviate your concerns or
apprehension?

It sounds like I am not the first person to want this feature and I
probably won't be the last.  I created the change for my own reasons, the
same as any other contributor.  I think we all know that I can not pull
out some chart and say, "This many people want this and here is why."  I
live in central Ohio and have been doing this as a hobby.  I don't even
know anyone else who knows about systems and operating system development.
If the justification that you are looking for is that I as some
hypothetical developer at a major tech company is about to release a new
RISC-V chip without M support but we want it to run Linux, I can not
provide that answer.  It sounds a bit like some software or hardware,
chicken or the egg anyway.  Trying to maintain my own fork if people
start contributing patches with incompatible assembly scares me.
