The platforms aren't too old, the compilers they run are.
All platforms are and will remain supported... I'm sure we can run the
code, we just can't *build* it.

As far as I can tell, there's no machines at all in the fleet with
C++14 or C++17 era compilers.
How do you selectively deploy tests to specific build machines?

I'm not sure what you're suggesting, I need to run the tests on every
build platform we have in the list, but we also need a recent
toolchain on every platform to perform the builds.
The build tools and the targat platforms are separate entities. I want
to test on all platforms, but we need to build with more modern tools.

There's no plan or intent to deprecate test platforms.
I intend to test on all of them... but how do I *build* the tests?
