Check out <https://music.stackexchange.com/questions/137874/lilypond-how-to-modify-stencil-by-automatically-getting-the-current-stencil-and> and its (currently) two answers while the second one (which was posted first) has not been removed.
This second answer has obviously been written by a capable LilyPond programmer. Compare its complexity and versatility with the first answer. Why hasn't a capable LilyPond programmer not been able to come up with a much simpler and much more versatile solution as shown in the first answer? LilyPond has received a lot of work to facilitate simple solutions, and yet the better approachability tends to rather lend itself to people becoming more confident designing overcomplicated solutions. What kind of project should we tackle in order to help people better use what is there in a manner that is reasonably easy to use and understand? How can we better spread best programming practises and showcase the tools that are available for them? -- David Kastrup
