It’s not lagging. How you install dep as conceptually nothing to do with how you link and build. You can tell dune to use dependencies installed with opam easily enough and opam takes care of managing and locking transitive dep. These are entirely different concerns. I am tempted to say "Kids these days" but that wouldn’t be condescending enough.

What is the actual gain of splitting dep management and build / link into separate tools? All I see is added complexity and ecosystem fragmentation.
