Of course technical concerns aren't directly relevant to making games, but they are still necessary. Productive development means overcoming technical hurdles, not only domain specific challenges.

What if you cannot adopt some library that would do something very useful because you lack the skill integrate or replace CMake or Bazel or Autoconf? Unnecessary technical constraints impact game quality.

What if due to insufficient automation the time between tests after making a very small change is 10 minutes rather than 10 seconds? Reduced productivity impacts game quality.
