> The ability to change which library is being used without needing to rebuild the main program is really important. In 40 years in the field, I've never needed that. Every single time, we just emitted an entirely new build - because it's _much easier._ > Maybe rebuilding the program isn't practical. Maybe rebuilding the program isn't possible because it's closed/proprietary or the source no longer exists These are edge cases. Nearly all the time when we develop, we are making changes in an existing codebase.
