Another way to look at this is that a contrib module is just that...
something contributed that someone thinks (and often is) will be
useful. If it doesn't fit what you need exactly then make your own
contrib module that does. Use what is there as a an example to do what
you want to do. I must admit that I've spent plenty of cycles working
out what a contrib module does and if it satisfies my use case, and on
retrospect it may have been just as easy to roll my own. YMMV, but I've
found myself getting in all sorts of knots trying to make something fit
when it's easier to just start from scratch and move on.
