I see your point, but I think Emacs could do better.

I second this: Emacs should skip markup in each major mode, and it is a
pity that the support for things like texinfo and/or org-mode is
somewhat poor.  This was my motivation to add a library to AUCTeX for
ispell and adjust most of it style files to use it.

True.  OTOH, Emacs could skip the markup where we know it can be
ignored, take for example @file{filename}.  Currently, both ispell and
flyspell try to correct the filename argument.  Here a nonsensical
example how flyspell looks in texinfo-mode with Emacs -Q:
