Following up with MDL-37479 and MDL-55580, I am toying with the idea of integrating some checks into the moodle local_codechecker to show the capabilities we want to deprecate.

This is at an early stage as I am not totally familiar with the PHP code Sniffer, but here is what I suggest:

• Step 1: we list all the capabilites we want to deprecate in the class and all the function/methods we might use to check for capabilities
• Step 2: We add the MDL-55580 features and we have a way to detect deprecated capabilities directly from core and the code sniffer will be able to find them this way.

For now I am in the early stages of step 1.
