Wasp has been trying to convince people to use their DSL for a long time. It's from the low/no-code era. I've never seen it anywhere besides their developer marketing on HN.
Custom DSLs that Ai's don't know about are a bad idea, and also generally for many reasons because they are hard to get right. You are going to have to feed the context in on how to use them for every message. Wasp may be ok here, as they predate the inflection point. They still have a knowledge gap / usage issue. No one really uses or wants the DSL, so there are few humans who can be in the loop to make sure it works as intended.
