We've added a solution for this problem in v0.245.0. There is opt-in "dynamic_version: true" flag on artifact to enable automated wheel patching that break the cache (Example). Once set, "bundle deploy" will transparently patch version suffix in the built wheel so that the new code is always deployed.

Note, that this only works with local wheels that are uploaded as part of "bundle deploy". So you need to download this wheel into your project so that it can be patched by "bundle deploy" before upload to break the cache.
