From the standpoint of a regular user, it seems like Unity Technologies takes longer than other big names in the game engine industry to put out new features and get everything ready for production. I've always wondered why that's the case. As an example, let's focus on SRP/URP since this Blitz day is all about Graphics. As far as I know, SRP has been around since 2017, which was the first time I ever heard of it. Why does it take more than 6 years to finish something like that?
