I don't know that it's that much easier today. I ran into lots of odd issues with Next.js and authentication and there wasn't a whole heck of a lot of useful info out there about it. Github does help, but you have to wait for the devs to reply.

There are tons of obfuscated Java jar libraries out there that are not upgradeable that companies have built mission critical systems around only to find out they can't easily move to JVM 17 or 25 or whatever and they don't like hearing that.
