I remember getting into a huge argument with some beardo at CMU CS because they were upset that people were sending mail with MIME attachments such as images "because they don't work in MH" even though it was in fact trivial to get MH to view graphical attachments and really what they meant was "i configured my email client in 1981 and i would rather inconvenience the entire world and reduce your functionality than learn a new trick".
Nonzero chance that @goob actually remembers this argument as a bystander.
