Eventually Community Tech will conduct some sort of community polling similar to those conducted by WMDE's #tcb-team In the meantime, we should build a work backlog based on one or more of the existing community wishlists, which can then be internally evaluated for feasibility, impact, risk, etc. (T105942).
Some existing wishlists to consider include:

The selected wishlist(s) should match as closely as possible the defined [[ https://www.mediawiki.org/wiki/Community_Tech_team#Scope | scope of the Community Tech team ]]. Preference should be given to wishlists which have already been ranked or prioritized in some way.
