Are you sure the lockfiles are platform-specific?

I spent a long time migrating a project to use poetry. One of the reasons I opted for poetry over others was that the lockfile retained all of the environment markers in the packaging metadata, so that the lockfile could support multiple interpreters and interpreter versions, multiple platforms, etc.

I can't speak for Poetry directly, but knowing how Python dependency resolution works: I don't think Poetry can make lockfiles not platform-specific, since package source distributions are allowed to (and regularly do) run platform-specific code for their own dependency selection logic.

For example, your package might depend on `foo`, which in turn could sniff the host OS and select the appropriate subdependency. You'd then end up pinning that subdependency, which would be incorrect on a different host OS.

(Similarly for Python versions: a subdependency might be required on < 3.7, so re-installing from a lockfile generated from an older Python could produce a spurious runtime dependency.)
