These issues are not TeX-specific, so they should be handled in a more
general way, not bound to TeX/LaTeX.  In particular, any "tex-skip"
features should not supplant the TeX support built into the speller,
they should only _add_ skip regexps for stuff that the speller cannot
support, like user-defined macros.

I'm not sure I understand item c), though: when and why would one want
to spell-check macros and environments?
