Add extensions

[TazorDE]

[LukasParke]

Triage update: keeping this as an enhancement, and adding question because the issue body currently has no details on the requested extensions.

This issue has also been inactive for quite a while (>90 days). Could you share more context so this can be scoped? Helpful details:

• what extension(s) you want to add
• expected behavior / example usage
• any relevant OpenAPI spec examples

If there’s no update after some time, this may be closed to keep the tracker actionable.
