would this be a "gentleman's agreement" amongst different manufacturers to keep ratings somewhat similar as some people shop rms ratings when buying speakers thinking that speaker "a" handles 50wpc and speaker "b" handles 75wpc so speaker "b" must be better?

While power handling is one of many criteria one must consider power handling alone is not indicative of quality. Choosing to purchase a speaker based solely on power handlign is like buying a cake because it is brown. That decision tells you nothing abot the cake, how it tastes, how mosit it is, what it is made from, how it is iced, shaped etc.
There is WAY more to it than that. I just make the simple point that you can't meaure power handling, but you can use it as a guide when selecting an amp that goes with it.
I should add, know for sure that PEAK POWER HANDLING is a virtually worhless number. It is there for the marketing folks and that is about it. Oh, and flea markets; they like PEAK POWER numbers....

Adding to the power handling specifications discussion...there is no governing body in mobile electronics to keep specifications honest relating to speaker power handling or amplifier power output. The authenticity of the specs are pretty much up to the integrity of the brand. The better brands are typically more conservative.
Many speaker companies use power handling rated for thermal capacity or the maximum amount of continuous power that can be maintained for a prolonged period where the speaker can still effectively dissipate the heat without suffering damage.
You can have two different brands of coaxials side by side with a 100 percent difference in rated power handling. Both have 1-inch voice coils with the same plastic former and the same gauge of voice coil winding. Neither has any method of special cooling other than a porous spider to exchange air as the speaker moves. Both copper windings and both enamel coil coatings melt and burn at the same temperature so there is no justification for the huge disparity in ratings. Its just a brand thing.
For a coaxial you can usually exceed an honest rating by a 15 to 20 percent margin based on the fact that you are usually running the speaker highpass and at least are reducing a good amount of the mechanical stress. You just have to stay away from hard clipping for the tweeter's sake. Certainly system set-up and tuning has as much to do with the power handling as the specs.
Like Phil mentioned, power handling is only a fraction of the story relating to the actual quality of any speaker. And, its often misunderstood. I'll take a speaker with 3 dB more sensitivity and half the power handling every time, particularly in an open boat.
