Missing component "Blink>ReportingObserver"

[jpchase]

The component "Blink>ReportingObserver" is missing from the list when editing a entry.

As in #496, this component is missing from https://blinkcomponents-b48b5.firebaseapp.com/blinkcomponents, and it's underlying source: https://storage.googleapis.com/chromium-owners/component_map.json.

Upon investigation, I see that component_map.json is populated by scraping OWNERS files in the Chromium code base. See https://cs.chromium.org/chromium/src/tools/checkteamtags/extract_components.py.

This is where we run into a problem for "Blink>ReportingObserver". The OWNERS file only supports one assigned Blink component per directory. The ReportingObserver code lives in a shared directory. We can't reasonably change the existing component mapping. In the longer term, it probably makes sense to move the ReportingObserver to a separate directory.

Regardless, it seems like a problem that the list of available Blink components in chromestatus relies on source code organization in Chromium. I would expect that if the components are defined in crbug.com, then they should be made available for selection when editing an entry.

Do we have any ways to query into Monorail to get a list of components? The indirection seems to be problematic here.

Yes, it's possible to use the Monorail API to get a list of components. I've been able to get that working in another project.
@jrobbins I can point you at the internal code (although it's in Go, I think there are Python examples around).
