      For big projects, especially open source ones, modularity isn't just good engineering practice. It significantly increases the chance of success of a project, because even if the overall project isn't popular subcomponents can be.

      Rails, split out of Basecamp, is an important example. Or ICU, split out of Taligent of all things!

      In my case, the biggest success of the Pathfinder project so far hasn't been Pathfinder itself but rather font-kit. I could have easily made it tightly coupled to PF, but then it would have far fewer users right now, because Pathfinder isn't yet done.

      Another example: Itanium may be dead and buried, but thanks to modularity it's also the reason you can throw exceptions in C++ and catch panics in Rust, because the Itanium C++ ABI became the de facto standard for open source compilers.

          would the Itanium stakeholders consider this a "success"? :)

          Probably not, but it's more of a success than all of the compiler work going to waste!

          If only Itanium C++ mangling wasn't absolutely horrible, and also underspecified in ways that are handled divergently by the LLVM and gcc camps :-(https://github.com/itanium-cxx-abi/cxx-abi/issues/68 …

          The Itanium ABI also has lots of mistakes that were regressions from the preexisting GCC ABI that would have been the de facto standard if a few ppl hadn't pushed to switch...

          See also: Java. I’m not sure these are really an argument for modularity, though, but rather more that it’s legitimate to try to re-solve “solved” problems as a part of other big umbrella projects.

          I wish @ChromiumDev did same. The views and aura frameworks are poorly documented and totally unusable except with chromium
