> Why discord domain verification instead of domain-verifications with a dynamic list on entries?

The TXT record itself is already a dynamic list of entries. It's far simpler and easier to iterate through the list and compare the start of each value with your search string until you find "discord domain verification" directly than it would be to do anything else.

Example:
