Even if getHeaders() has security/performance concerns, the better solution is to make it an alias to the newer headers.get() in this case. Keeping the old API is a small hassle to a handful of developers but breaking existing code puts a much bigger burden on a lot more users.

Ya, why not just alias old api calls to the new if implementation details changed?

If you (either directly or from SerpApi) are supporting the urllib3 folks (through a Tidelift subscription), then yes, that is a valid point.

Otherwise, I'd say that's a very brave comment you are making.

"Brave" in what sense? It's a legitimate question why an API is having a pattern deprecated and removed for what appears to be pattern reasons.

If he gave money valid point if not he must be brave?
