Bug Too much space is used for new 2D projects (2021.3.16f1 LTS windows 11)

There is a difference between new projects created via 2021.3.16f1 LTS and 2020.3.44f1 LTS.
I tried to create new 2D project using different versions of Unity and found out that:

2021.3.16f1 LTS uses approx 1.25 GB
2020.3.44f1 LTS uses approx. 260 MB

Btw 2022.2.0b16 BETA uses approx 1.25 GB

Why so?
Why is 2021 Unity not using local cache from user directory? how fix that annoying issue?
Thanks

 

Might be unneeded package crud. Otherwise, list the files and compare them to see what has been added, see if it can be removed.

Extra unwanted packages in new projects (collab, testing, rider and other junk):

About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:
