Org-Cleanup with Sub-queries - Make it fast and elegant!

Sub-queries are so under-utilized! Something simple like give me all Contacts to an Account but only for Accounts with recent Opportunities is simple with sub-queries, but becomes a maze of Maps.

I understand, for many developers (AND AI) the map way is just so familiar, but think about the elegance a nice SOQL brings.

As part of any clean-up: Move wherever possible from a maze of maps to a simple, elegant SOQL query can make reading your code sooo much faster and simpler.
