If frequency boundaries weren't on charts, it would be even more stupid than it is now! At least people flying around in the same airspace should know what frequency is most appropriate for their situation.
Yes, by all means, let's get 126.7 in use as the multicom for airfields that don't have another freq specified, but why all this hoo-ha about getting frequencies off charts so we can be like the US? Storm in a teacup. However, Dick always has an agenda, so I guess we will see what transpires.
