Your comment about libraries is quite relevant still - it's about an ideological preference where you preferably would not have many libraries in the ecosystem that do a similar thing without one of them being the default obvious one way to do it. "Batteries included" philosophy is one aspect to ensure that this happens, preferring to have a 'blessed' way to everyone choosing a different library which gets the advantage of each being slightly better tailored for the need at the (significant!) cost of fragmentation and thus readability and maintenance.
