All things being equal I agree, however there is a maintenance burden
for the QEMU upstream, especially if the only active use if on
out-of-tree branches or behind the closed doors of research groups.

Looking at https://wiki.qemu.org/Documentation/Platforms/TileGX it
doesn't give much of an idea of where I would get toolchains to build
guest binaries or what guest user-space I could run.
