You cannot apply RFC 2119 pedantry when reading older RFCs. Especially
when reading RFC 1035 you will be more correct if you treat "should"
as having the force of MUST unless you have clear evidence otherwise.
Also you can't ignore updates to RFCs; in particular the part of RFC 1035
you are quoting is amended by RFC 1123 (STD3) and RFC 7766.

Cromarty, Forth, Tyne, Dogger: West 4 or 5, occasionally 6 at first, then
becoming variable 3 at times. Slight or moderate, becoming smooth or slight
later except in Dogger. Rain at times. Good, occasionally poor in Cromarty.
