Have you learnt nothing over the years?
One of the main problems with OS software is that it decays. OK maybe not with Linux or Apache but other stuff? So you've found some OS software that does its job today, but next year the developers are off doing something else and what you have is abandoned ware. Maybe you don't notice this has happened, after all you have no maintenance renewal, indeed nothing to indicate that the software has tumble weeds blowing through it. Have security flaws been found in it? Does it use other bits of OS code that was found to be pwned? You really don't know.
