I have found out a few extensions that are apparently deployed to Wikimedia but have their CI jobs relying on composer to install dependencies. They should be switched to use `mediawiki/vendor` instead.
There are:
[x] TemplateStyles
[ ] MachineVision
[ ] PropertySuggester
[ ] WikibaseQualityConstraints
[ ] Wikidata.org
[ ] ~~WikibaseJavaScriptApi~~
[ ] ~~WikibaseQuality~~
[ ] ~~WikibaseQualityExternalValidation~~
They are configured in integration/config with the composer variant of the job, and there is even a FIXME for them. Example:
```
lang=yaml,name=zuul/layout.yaml
- name: mediawiki/extensions/MachineVision
template:
# FIXME: Document why this is using the composer variant.
- name: extension-quibble-composer
```
That should be `extension-quibble-vendor`, or due to T232759:
```
- extension-quibble-noselenium
- extension-quibble-only-selenium
```
