Extend Variable Library to include Functions and Web activities

It would be great if you could extend the use of Variable Library parameters also to Web activities in Fabric pipelines, as they use Web connections that can vary from one Workspace to another, especially if it is between Development and Production environments.
We believe it is half of the solution to take care of Variable Library parameters in Copy activities and not in other activities that use connections.
Activities that will benefit from Variable Library usage are:
1. Web activity
2. Functions activity
3. Invoke pipeline activity
4. Webhook activity

Thank you.
