I've been using H/M/L since before Vim existed. Frequently PgUp/PgDn did
not work without a manual :map in those days, and many keyboards I use
even today lack those keys. I am the sort of person who uses ssh from
a phone with an on-screen "soft" keyboard. Every motion that doesn't
require switching keyboard panes is my friend.

And as someone who has used H/M/L since before Vim existed, consulting
the H/M/L documentation for how those would behave with a "{not in Vi}"
setting didn't occur to me. {not in Vi} settings SHOULD document their
not in Vi behaviors at the setting level.

The motions H/M/L are the only ones that operate based on what is
*visible* on the screen. It is my firm belief that changing those motions
to ignore parts of the *visible* screen is seriously against the spirit
of the motions.
