Coling:

According to the announcement is that the two "camps" have agreed to ensure API *compatibility* between the two versions of RISC OS, which is a far cry from agreeing to match one another feature for feature.

What I believe this means (for a very simple example) is that if in one strand someone adds a new function to OS_ArbitrarySWI and uses previously unused reason code 666, then rather than the other strand having that same function added (which, as you rightly say, can't be guaranteed to happen) what will actually happen is that reason code will be, effectively, "reserved" (for want of a better word) for that same function - should someone be willing/able to add it in future - and won't be used for something else in the other strand.

So, as a developer, you can be sure that calling OS_ArbitrarySWI with r0=666, you will either cause Damian to appear, or nothing will happen at all. It won't, in the alternative strand, cause an unexpected pizza delivery.
