deprecations and their
status

2. Experiments

3. The EXPERIMENTAL idea
Experimental code is disabled in builds by default
Discouraged from use in production
Allows us to ship code earlier (not 100% there)
Gives room to fix initial blunders
@bagder

4. Current experiments
Hyper
HTTP/3
CURLSSLOPT_NATIVE_CA
The headers API
Rustls
WebSockets (?)
@bagder

5. Problems
Disabled in builds means barely anyone tries them
Virtually no feedback on experimental features
No clear point when to toggle it off
@bagder

6. Improved experiments
Provide experimental binary builds?
@bagder

7. Deprecate

8. The DEPRECATE idea
Features / dependencies that aren’t in use anymore
“Trim the tree”
Must be possible to drop “nicely”
“Warn” at least six months ahead of time
@bagder

9. Current deprecations
NSS
NPN
