Description

I had the idea of having `Layer` and `Glyph` cooperate to check that inserting, modifying and removing components ensures that we never end up with dangling components. [glifparser has code for handling](https://github.com/linebender/norad/issues/107#issuecomment-997388325). Need to investigate:

1. Does it add value?
2. Should it be used for UFO loading or just for the programmatic API? When loading UFOs, how to handle glyphs that exist but aren't added yet?
3. Are there situations where you'd need an unchecked way of messing with components?

Research direction

Start by reviewing the Layer and Glyph component-handling entry points and the linked glifparser discussion. Investigate whether checked insertion, modification, and removal add value, how they interact with UFO loading, and whether an unchecked API is needed. Done means the API scope and loading behavior are decided and documented.
