Yeah that's a bit of bummer with these run time dependencies.

I realized that the redis cache store also requires 4+:
https://github.com/rails/rails/blob/0d30e84878223df68efda3b0e1741611d9682a45/activesupport/lib/active_support/cache/redis_cache_store.rb#L4

So maybe it is safe to say if you use redis to have at least version 4? I don't think it's a breaking change from 3.x and has been released in 2017: https://redis.io/blog/redis-4-0-0-released/.
