Experiment with use of Technical Writing label on issues and report back to team.
Within the Ecosystem group, require that for a documentation issue to land in a milestone, whether ~Backlog or an numbered milestone, establish whether the primary author will be TW or Eng via the presence or absence of the ~Technical Writing label. This will help establish earlier in process what needs work from the TW.
Ask TW team if others do it a different way. Document - perhaps as a stage/group process or option for all TWs - if it works.
