It is really surprisingly that programming society managed to get by for decades and build an incredible number of things without these details. Wow. What really happened is the people (or person) who needs to find what they needs to find, always finds it really damn quickly because it is already domain-knowledge in the area they are working, they edit a Maefile, and carry on. Once it is encoded into the Makefile ,note it is usually the same value on every operating system and if it isn't we all know make(1) doesn't read manual pages. That Makefile gets copied around to other systems. People pass on the domain knowledge organically. There's really no drama here. However, adding 3 lines (including the blank) to a ton of manuals, that is drama. Because obviously there'll need to be a Task Force to go on this Mission and splatter the shit everywhere. This is not like lines describing #include files, because those are different for every function in every manual page. So I personally think it is a fools errand.
