I believe I read a thread that talked about excessive pressures to the frame and so they will not make barrels in those calibers. Don't quote me though.

You know, as I thumb through my Hornady 6th Edition loading book I can't see the mystery of these short mags. The numbers are the same for 300 win mag vs the short mags the same again on the 7's. The only difference I see is the old school calibers are far more powder tolerant and can make their numbers with a far greater variety of powders.
I have 2-375 H&H barrels for my Encores, if a 270, 300 or any of the short mags is making more pressure than those beasts heaving a 300 grain bullet I can't see many people shooting the gun twice. I don't believe for a second that the frame can't handle it. What I do believe is that the short mags aren’t selling very well and there is most likely a wait-and-see attitude to see which if any survive before T/C chambers them.

What you see is the limited number of powders the Hornady folks tested, not a limit to the number of suitable powders.  They have had decades to develop loads for the .300 WinMag, but only a couple years for the .300WSM. I agree that these new cartridges are not "needed", but that really isn't the point is it?  Who really needs more than half a dozen rilfes anyway?  I don't - but I own far more than six.

You are confusing pressure with recoil.  The short mags are loaded to about the same pressures than the .375 H&H is....
.375H&H = 62,000 psi
.300WSM = 65,000 psi

While "belief" makes the world a better place to live - you're dead wrong here.  The frame is about maxed-out with the .375, and is not safe with the larger diameter WSMs, etc.  
.375H&H = 0.513" diameter
.300WSM = 0.555" diameter
In rough figures, this means that the .300WSM exerts 27% more force (not pressure) on the frame than the .375 does.   That is why they do not chamber for the WSM, RUM, and other cases of similar diameters.  

In this instance, science triumphs over belief.  Fortunately, that isn't always the case.
