I don't see why. C is not a complicated language, and a large part of
the Emacs source code never touches its relatively more problematic
parts, like memory allocation.

This is a red herring: the C-level internals are extensively
documented in comments to the respective source files. Many source
files have large commentaries at their beginning describing their
design and implementation. Having those in Texinfo will not change
anything.
If someone comes up with a list of specific design aspects that are in
their opinion under-documented, post them. I'd be surprised to see
there anything that someone active here can tell which isn't already
in the comments, but who knows.

So not really relevant to the issue at hand.

Likewise.

No one needs to hack on code specific to these platforms if they don't
feel like it. Our problem is falling behind on Posix platforms, not
on the rest of them. Most of the Emacs internals are
platform-independent anyway. Just pretend that this issue doesn't
exist.

There's no other practical solution except volunteering and getting
your hands dirty. Knowledge and experience will come with time.
