Are signals and trait expressions case sensitive?

Hello,

Yes, signals & trait expressions are case sensitive: https://experienceleague.adobe.com/docs/audience-manager/user-guide/features/data-explorer/signals-s...

If traits are case-sensitive, then why can't I create a trait and keep it the case it needs to be for future data coming from our data warehouse?

.. as well as rule-based traits, which you can also test using the Test Event URL Tool in the Trait Expression Builder:
