I'm afraid so. I've worked on a good many networks where everything is in one VLAN; a common argument for the practice is IP assignment granularity. Rarely do I find MAC ACLs in place at the switch. (I'm actually trying to remember a specific installation that had MAC filtering set up by a prior engineer... I'm _sure_ I've encountered at least a couple.) Note that these observations are for small- and mid-sized networks. Maybe things are better in the larger networks. YMMV.
