I understand you but DSLs allows to reduce number of used languages/tools in a web-projects.
For example NodeJs allows to use same JavaScript for both client and server and if we will have smth like http://lispyscript.com/docs/#templates we can also seamless export business logic into templates (without need to create special template tags, filters, syntax, etc).
Single language for almost everything can be big performance boost IMO.
