Context

The order in which extensions are loaded is important. If the order of extension loading is different in a local environment compared to production, it's possible to encounter bugs that are not reproducible in a local environment. (See T20110 for an example of ConfirmEdit/AbuseFilter interaction.)

Proposal

• Provide an API query module that returns a list of enabled skins and extensions, using ExtensionRegistry::getAllThings().

Consequences

• It will be possible to use the CLI to make a request against production and a local instance and diff the two arrays, to show discrepancies in the order in which extensions are loaded
