[discussion] Preparing v7

[MBilalShafi]

This is an umbrella issue that centralizes and lists all the potential improvements that we can consider in MUI X v7. The potential improvements being listed here require breaking changes. We do intend to ship v7 in the coming months. We plan, as much as possible, to release the next major features in minor versions without breaking changes.
