What about an archive project feature?

Unity generates a lot of 'temp' files as you develop your project, they are only needed for quick loading and developing/building to target platforms.

With older projects these files will just need to be regenerated if you open them in a new version of Unity so an 'Archive' or feature would allow developers to park their shelved or old projects keeping only the main files and taking up less space.

Ideally an option to compress all of the remaining files into quick to access/unpack 'packages' of some kind that could maybe be used as template or starting points for new projects would be very helpful as well.

So Archive Project feature in Unity Hub with the aim of reducing project bloat and potentially making our own frameworks/templates/base projects easier.
