Yes DSLs have been a terrible failure in the infrastructure space. But that's just because DSLs are suited to a class of problem where the language of the domain is well-defined and changes infrequently. What we've seen with devops is an ecosystem that changes even more rapidly than frontend software development (in other words, a brakeneck pace). DSLs are great in any area where you want to allow less-technical or untechnical users generate some simple rules. So think finance teams using Microsoft Excel, or video game story writers using in-house DSLs to define game events.
