Why? If we want to support older newer kernels running on older distros,
which is a valid goal, or recent tool source code on older distros,
where fallbacks will take place with their older kernels, and if we have
the build automated for that (I have) then why not keep the tools
building on as many different userspaces as possible?
I'm not even putting this as a burden to you, that may choose to support
only recent systems, but since I have this automated and can catch such
problems, I intend to keep the tool building in as many systems as
possible.
The good thing about my report was that you noticed a problem in
existing code, i.e. the 'perf trace' beautifier that was working only on
x86, thanks for that!

Right, I understood your intention, to have both independent.
