Following the merge of https://github.com/bitcoin/bitcoin/pull/23083, we'll throw a non-fatal error at runtime if the documentation for an RPC is incorrect. This behaviour has found numerous issues over a very short period (of the PR being opened). However, this is not something that we want in production / release builds, instead, we want the ability to have it enabled in the CI and when running tests. A runtime option could be added, which controls this behaviour (disabled by default).

#### Useful skills:

- C++
- Understanding of Bitcoin Core's initialization sequence
- Understanding of Bitcoin Core's RPC interface
