Where can I see this agreement?

Well it also says:
"""
If a platform is not listed here, it does not imply that QEMU won't
work. If an unlisted platform has comparable software versions to a
listed platform, there is every expectation that it will work.
"""
A lot of downstream have customized build scripts.
Still Linux versions older than 2.6.35 do not look like "comparable
software versions to a listed platform" in my opinion.
And is something similar to such removal that has been done for other
subsystems?
With commit c42e77a90d ("qemu/osdep: Remove fallback for
MAP_FIXED_NOREPLACE"), I remove the support for glibc older than 2.28.
Linux 2.6.35 is even older.
