man(1) says:
MANPAGER
If MANPAGER is set, its value is used as the name of the program
to use to display the man page. If not, then PAGER is used. If
that has no value either, /usr/bin/less -is is used.
Do you plan to fall back to PAGER when CRASHPAGER is not set?
No, because of the reason I mentioned earlier, that being an
environment of "PAGER=/usr/bin/less" completely screws up the
user interface.
