I think context matters.
In the context of BOM, it's a popularity contest so I don't get where performance is an issue. I don't mean this as a criticism, and not like a "beauty contest" for the bowyer. Rather a particular bow might be appealing to more voters for any number of reasons other than performance. In fact the one bow I've made that I recall winning BOM looked really purty with walnut overlays and such and an nice symetrical tiller, but it actually doesn't shoot as well even as most of my other, considerably more humble or "ugly" projects. I've always been amused by the irony of this.
In another context I think it's important for some to carve out a niche in this business to differentiate product, and pa and paleo try to draw a distinct line in what in reality is a shades of grey question. There will always be a spectrum of intestest and experience. It's probably more important to embrace the "big tent" than to further segregate an already small community. After all, how much different is a bow designed by formula, by computer computation actually, created entirely by use of precision machine tooled lams and epoxy from a conventionally trial and error tillered simple composite w/ a strip of phelonic in the handle, for our purposes here. Don't we value conventional methods, as well as materials, at least to some degree.
For what it's worth, I don't see the use of phelonic as having has any reason or purpose or justification other than aesthetics, and as such barring it from use in the context of PA and it's BOM as not being much of a burden. If such a restriction, in particular retroactively, creates some inequity for one individual one time, then grant a waiver... or better yet just let the voting in BOM reconcile it's relative value or appeal.
