This will enable us to support sentence editing/content transformations and I suspect things such as re-positioning components such as infoboxes on small screens.
Initial thought is we'd aim to do this in the "beta" channel of mobile first, and then roll out from there.
We are aware that Parsoid has no support for video and audio tags right now, but given support in mobile is currently low (and broken) given the expected performance benefits this is an acceptable trade off.
Concerns that need to be addressed:
- How is audio and video impacted? https://phabricator.wikimedia.org/T64270 and how does this differ from existing experience
- How does this impact editing? (I would suspect no impact on short term, possible impact on long term)
