I think it's the same rationale as with other buildfarm animals
representing niche systems: we make the effort to support them
in order to avoid becoming locked into a software monoculture.
There's not that many compilers in the farm besides gcc/clang/MSVC,
so I feel anyplace we can find one is valuable.
As per previous discussion, it may well be that gcc/clang are
dominating the field so thoroughly that nobody wants to develop
competitors anymore. So in the long run this may be a dead end.
But it's hard to be sure about that. For now, as long as
somebody's willing to do the work to support a compiler that's
not gcc/clang, we should welcome it.
