How Has This Been Tested?

This looks reasonable, but the get_all_protocols endpoint naming compared to the contents of the response is confusing to me. Awaiting your response before approving

Aside from the nit about an unused ACAS_LSTHING constant, this LGTM. Let's spin off the refactor to a separate PR, especially since this code is already tested through the migration.
