There is, as of 5.0. Which, 5.1, is going to ship with Boost 1.85.

That's possible. We just need to add "require-b2 5.1 ;" to
boost-root/Jamroot (or any other jamfile). Which this PR
(https://github.com/boostorg/boost/pull/854/files#diff-ea2703244a4dec1e6f7bfe7f4f4836c65eef03591dc6cb55df0be57de4c38b57R125)
will do once I get the final testing on that done and it gets merged.

It's not. I test every change to B2 with Boost versions from 1.66
onward (although I need to add 1.84 and 1.85 when that's released)
plus develop and master branches on Windows, Linux, and macOS. For
example <https://dev.azure.com/bfgroup/B2/_build/results?buildId=1157&view=logs&s=b4a2ddcd-11cb-5970-1bbf-f636351df511&j=3ad4e34e-ab49-518a-e310-16a369583b97>.
Which means you can use the current B2 with every version of Boost
released in the past 7 years.

Please, I implore you, submit a bug with repro steps to
<https://github.com/bfgroup/b2/issues>.

B2 has had a rather large test suite for close to 2 decades. But
testing build systems is challenging. :-(

Already the case. But maybe you mean something other than providing
backward compat?
