Eventually Community Tech will conduct some sort of community polling similar to those conducted by WMDE's WMDE-TechWish. 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:

https://bugs.wmflabs.org/buglist.cgi?columnlist=product%2Ccomponent%2Cassigned_to%2Cbug_status%2Cresolution%2Cshort_desc%2Cchangeddate%2Cvotes&list_id=361519&order=votes%20DESC%2Cassigned_to%2Cbug_id&product=MediaWiki&product=MediaWiki%20extensions&product=MediaWiki%20skins&product=Wikimedia&query_based_on=&query_format=advanced&resolution=---&votes=2&votes_type=greaterthaneq
The selected wishlist(s) should match as closely as possible the defined scope of the Community Tech team. Preference should be given to wishlists which have already been ranked or prioritized in some way.
