I am not sure about this failure: https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/1a538ed11284d3a47bf9851621c653c567cbc1a3/variant/compilers,4.14,lwt.6.0.0,revdeps,osc.0.1.4

Do you think it has anything to do with this PR? If not, I think we can finally merge

I don't think the failure is from this PR. See #29147 (comment) for previous discussion. TL;DR:

• older versions of lwt already mention mutex
• i think it's changes in the build system which makes it necessary to explicitly mention some cli flag to get mutex

also note: the package is in avoid-version (#29185) (following identical failure in previous lwt release PR)
