What you're saying is true, but I think a big problem in general is that while bespoke problems often require bespoke solutions, there's a lot of common problems out there and using a common solution goes a long way. They make the pitfalls and limitations obvious, help greatly in staff turnover and growing your team, and make things more intuitive and consistent. I see a lot of systems that work pretty well when the author maintains it, but someone else jumps in and has no idea what server some part is running on, where the credentials might be, or where the log file is.
