We did not roll back our dependency, no, although our current release (3.4.x) allows you to disable Rust compilation via an environment variable specifically so we could understand where in the ecosystem challenges would occur. Our next release (now 35.0 based partially on feedback from the community around our unusual versioning) will hard depend on it for all X509 ASN.1 parsing. During the months since we did our first rust release, however, the `musllinux` specification and implementation has been finished so we expect to be able to ship binary wheels for Alpine very shortly. I am actually working on that today, with the only remaining blocker being an update to warehouse to allow wheel upload.
