That seems like a pessimal way to make things interoperate: use one of an unknown set of algorithms ...
Given that we're already working in an environment where it's unlikely that everyone's working from a common version of the PSL, I don't think this is such a scary idea.
But one of the points of the tree walk is that for the first time it gives us a well-defined algorithm that everyone can use to get the same answer.
I realize that the PSL works OK, mostly, we think, give or take its daily updates and no agreement about whether you use the whole thing or just the nominally more official first part. I don't see why we would want to make things worse.
