@SuricrasiaOnline You might like George Sheldrick's "Zero dependency philosophy"; every program he writes is 100% stand alone, no dependencies other then the core libraries of the language (and at the start, not even that!)
That's let him maintain Shelx since the *early 70s*. Like, he still puts out new versions of it when the first versions were distributed by *mailing people punch cards* (I believe it has had two-three major upgrades in the 80s, 97 and 2013), but still by sticking to whatever the basic Fortran features were of each era he's made this thing run on everything from 1970s mainframes to PDP-11s, to WIndows and Linux to Android!
