Yeah, I want a low bar for doc building too. The initial hack fest we had
to add cross-linking and other dearly needed stuff increased the build
time so much that everyone stopped creating docs. It's of course not as
extreme, but stating that "no one runs the doc toolchain" is imo akin to
"no one runs gcc, developers just read the source and users install rpms".
It's totally true, until you try to change stuff, then you have to be able
to build that pile fast and with an easily-obtained toolchain.
