No. mvo pushed https://salsa.debian.org/apt-team/apt/merge_requests/6 to implement waiting (in the src:apt frontends), but that's just busy waiting. For our own frontends like that we could implement non-busy waiting using LOCK_EX without LOCK_NB and setting a SIGALRM to cancel the lock attempt after a timeout[1]. I don't really think that's reasonable for a library to do, though.
