Motivation 🔦

User requests:

• https://mui.zendesk.com/agent/tickets/6179
• https://mui.zendesk.com/agent/tickets/8495

Distribution opportunity:

• The Figma team is looking for high quality design files to include into a starter kit. They contacted us, see https://groups.google.com/u/1/a/mui.com/g/team-design-kits/c/Ht80CJUhrSM. However, not until we use the latest Material Design spec

But this might never fit since we our goal are different from Material Design, Material UI is following a close but not identical design spec.
