Looking for plugin replacements for JavaScript GUI Lib

Jenkins Version: 2.303.3
Java: 11.0.14

We are looking to cleanup the deprecated plugins from our Jenkins Service.
We couldn’t find any possible alternatives for the listed Jenkins Plugins.

Async Http Client (async-http-client:
JavaScript GUI Lib: Moment.js bundle plugin (momentjs:1.1.1)
JavaScript GUI Lib: ACE Editor bundle plugin (ace-editor:1.1)
JavaScript GUI Lib: Handlebars bundle plugin (handlebars:1.1.1)
JavaScript GUI Lib (jquery-detached:1.2.1)

Can these plugins be deleted directly or the functionality can be given through a different plugin?

These are library plugins. They don’t add any features to Jenkins, but are used by other plugins. If you can uninstall them from the plugin manager, you have no plugins left which need them, and can proceed with the cleanup.
