How to perform modifications on bins handled by succinct hash bin delegations?

Description of issue or feature request:
Currently, I am working to support succinct hash bin delegation as described in TAP 15 in Repository Editor for TUF.
Repository Editor for Tuf is a CLI tool that tests the usability of the public API calls provided by python-tuf while also providing a good hands-on visualization approach to learn about python-tuf and the TUF specification as a whole.

While working on it I came up with the following question:
how do we want to approach changes related to delegated bins represented by succinct_roles dictionary inside a targets role?

For example, what should we do when a user wants to do the following in a bin metadata file:

1. add/remove a new key
2. change threshold
3. bump expiry
4. add/remove a target
5. add/remove/edit delegation
6. bump version

I want to discuss it with everyone who is interested but will especially love to hear the opinions of the maintainers.

Inizia leggendo TAP 15 e il Repository Editor per comprendere il contesto di TUF, poi esamina come succinct_roles rappresenta i metadati di bin in un ruolo targets. Esamina le sei operazioni proposte e la discussione esistente per determinare il comportamento desiderato; l’issue sarà completa solo quando i maintainer avranno concordato un approccio.
