This problem is easily solved by just having an external cooling solution like a USB fan tray that sits under the MacBook, and only when you are doing some heavy tasks. In normal day to day use most people will not do enough processing to be affected by thermal issues.

People take for granted how much we’ve improved on old big and heavy laptops (with worse performance even).
