I feel like Antirez has already done everything needed to ensure this doesn’t happen, by 1. building the module system into Redis, and then 2. working with companies like Redis Labs to establish that Redis is enhanced through these modules, and to ensure that modules offer everything required to enhance Redis in all the ways that matter.
In essence, Antirez has protected the core of Redis from needing to bloat, by making it possible for anyone who wants to build on top of Redis to literally do so—build on top, rather than inside. As such, I expect future PRs to Redis Core to look much like current PRs to Redis Core: just fixing bugs, adding stability, and resolving infrastructure-level interoperability concerns.
