Sourcegraph CEO here. The market does care, and there are a lot of companies using (and demanding) deeper Sourcegraph integration with code hosts, via things like our browser extension (https://about.sourcegraph.com/docs/features/browser-extensio...), Phabricator integration (https://about.sourcegraph.com/docs/features/phabricator-exte...), and built-in integrations.

We've been so busy and haven't published much more about it yet, but there are large tech companies using these to get Sourcegraph integration right inside their code hosts. The feedback from our customers is very, very positive on these.
