Continuing support for Learning Lab custom courses?

Hello! Does anyone from Github or the community have news or information on continuing support for custom courses in Learning Lab?

My team has created our own Learning Lab courses in the past for onboarding and teaching data pipeline tools, and found them to be quite useful. However, the change to no longer allow making custom courses public in ~2020-2021 has made custom courses much more difficult to share across our organization (e.g. Learning Lab: sharing your custom courses now that they can't be "published"?). This has raised some questions of whether Github plans to continue supporting custom courses, either through free or enterprise Github, and whether we should continue investing in them for other training materials.

Any news or advice would be appreciated!
