Hey, clicking around that Wiki it has some pretty interesting information. Do other large open-source projects have a very similar workflow?

You mean having full-time engineers handling merge conflicts / upstream breakage / regressions / running test suites? In anything sufficiently large, that becomes a major issue inevitably.

Almost any project worth its salt has someone doing testing. But it is really time consuming.

The most significant long term upstream-downstream relationships are probably the linux distros to the kernel.
