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.

Beginne mit dem Lesen von TAP 15 und dem Repository Editor, um den TUF-Kontext zu verstehen, und untersuche anschließend, wie succinct_roles in einer targets-Rolle Bin-Metadaten darstellt. Prüfe die sechs vorgeschlagenen Operationen und die bestehende Diskussion, um das gewünschte Verhalten zu bestimmen; das Issue ist erst abgeschlossen, wenn die Maintainer einem Ansatz zustimmen.
