There are plenty of very popular libraries that are low quality and/or have some major issues, popularity of a package is not necessarily indicative of a perfect design. When you put something into your language standard to be supported for the next 30 years you want to make sure it’s as correct for as many people as possible. “Oh this seems to work fine let’s merge it” is not a high enough bar.
