If's completely possible to have TeX files with typos in the macros or
environments.  I wouldn't mind having some mechanism for detecting
such typos and suggesting correct possibilities.  Whether that should
be done through a spell-checking interface or not, I don't know.
Obviously I'd want the dictionary for spell-checking those lexemes to
be distinct from the ones used for checking ordinary text.

Please note I am not advocating for such a feature, I am only
responding to your question.
