Very much agree. You would actually be cheaper running a separate 120v line where you need it and be IN code. 4 wire is expensive. Along with added cost of the outlets and plugs.
Keep the voltages separate.
And for my two saws that are 240v I just use straight plugs. Twist lock are twice as expensive and really don't help in most instances. For my two older RAS and my lathe that are running off VFD and 240v I just use again straight plugs which are easily disconnected to power down the VFD.
