The review-rate on GitHub is almost non-existent. Apparently nobody even notices there are patches waiting for review. I currently have 69 (!) patches on GitHub waiting for review, see https://github.com/search?q=is:pr+is:open+author:thiemowmde. Most of them so small that it should take minutes to review and merge them, but some are just sitting there for weeks and months. This is getting frustrating. Linking these patches to Phabricator tickets barely helps. Sometimes it just doesn't make any sense to create a ticket for a patch that's so small that it's basically a no-brainer. In other cases where I link patches to tickets they don't get reviewed either.
The only final solution I see: Move everything to Gerrit so I can add people for review. This is not possible at all on GitHub and I consider this the main reason why GutHub is just bad for what we are trying to do in a team.
Intermediate solution: Merge all DataValue components into a single one. The way this component is split doesn't make much sense anyway. Some interfaces are in the "Interface" component, but others are in "Common". Some data values do have their own component, e.g. Time and Geo, but others are bundled in "Common". Why? Also see T92268.
