I think we can debate this forever if we want to, and of course when product families change owners (or when companies merge or change names) it will be tempting to rename or move files. But I think we'll treat this the same way as we do with bindings and other aspects of the kernel: some platforms will have legacy names that might not describe their current state but documents the lineage of the product. For that, it might be slightly easier to use product family names instead of company ditto, but I really don't care enough to request changes. Also, since the subdirectory doesn't influence install path on 32-bit, renames shouldn't be the end of the world (but I'm likely to turn down those requests beyond the possible initial "we miscategorized this platform" kind). -Olof
