So the workarounds could be:
a) Allow users to configure the order of remote build cache bs GitHub-based remote build cache (e.g. try S3-based cache first, and GitHub-based cache later)
b) Allow users to configure regexp of the task needs to be cached (e.g. cache .*test.* only)
c) Implement throttling in the build-cache proxy (e.g. respond with "not found" for requests coming too often)
c) Disable GitHub-based remote build cache by default (==revert to old file-based caching approach)
