You are right I also think making this no-op is the best way for now. Notably, Symfony HttpClient uses the constant to **disable** this feature. So if we were to deprecate the constant, it will cause deprecation notices unnecessarily. > > But regardless of deprecation or no-op'ing, we should document the > behavior, and tell users about alternatives to accomplish the same goal. I will submit PRs to the php/doc-en about the outcome of this change. Thank you for weighing in on this. There is PR 5094[^1] from you that proposed to deprecate several `CURLE_` constants. If we were to no-op this constant, I'd like to propose a deprecation RFC with all those changes combined. Thank you, Ayesh. [^1]: https://github.com/php/php-src/pull/5094
