Out of those xx% of projects, how many really need the flexibility? Based on the last 30 years or so of being a developer, I would be tempted to believe that it would be in the low single digits. It is sometimes worth it to spend a little extra time as you set up the build process, and as you make decisions on how to organise things so they can conform to a build process other people will understand. Quite often "clever" builds on long-lived projects, or projects with many developers, have a higher cost in terms of effort than what you save on "clever" shortcuts.
