Can we shrink Project storage even more?

I was noticing when working with larger projects with many cells and records, that the file sizes themselves in the workspace can get a little bit "large". And when you are working with tens of them, GB's of disk storage can be gobbled up.

Was wondering if we can somehow pack bytes perhaps more somehow?
Would this help in places and if we used base64 ? Convert an Object to a Byte Array in Java | Baeldung

Any other ideas to shrink disk storage itself for projects?
Higher, better compression algorithms for saving projects? (yeah, storage is cheap, but not when your running out of drive space!)
