I don’t think you are being fair. This question presupposes that the supposed problems can be solved by iterative changes, rather than being inherent in the chosen design/architecture of the software, which usually requires complete replacement thereof (as well as the leadership thereof, as people who choose poor solutions to problems often can’t appreciate arguments for superior solutions).

(Not that I’m trying to suggest that I agree that homebrew in particular is bad — just speaking generally.)
