Semantics aside, I think you misunderstand my point.
A good number of players/dm's that I've met weren't aware that you could do a move action that isn't movement (ie: drawing a weapon, pick up an item, etc), a standard action (ie: one attack, cast a spell, etc), and a 5-foot step all as one round. They were under the impression that a any move-actions disallows a 5-foot step. Thus, they thought that 5-steps are mostly used only for full-attack actions.
Personally, I can't imagine playing a game that way, but it seems a common misundestanding (I know two groups that have been doing it that way since the beginning of 3.0, until recently). Anway, it seems to be a fairly common misconception... I'm trying to figure out why. I think part of it is the naming convention. Why not simply name Movement actions, Partial actions (or something else). The "movement" part of Movement actions might be causing the problem.
