As other people stated, yes, it is very time consuming to get it straight. Treat it as a hobby, you'll understand things about the Mac (or computers in general) other people don't, such as DSDT patches, how drivers are loaded, and Mac power management, etc.
If you use Clover, and get all the patches right, you can almost get an update-proof setup (Except when you go from say 10.11 to 10.12). But even at the worst case, usually people on the Internet will figure out fast enough for you to apply the new patches. Minor updates are really really easy and fine. I always click Update without batting an eye.
It's a tinkerer's hobby. If you like doing researches and being fine with spending time figuring out stuff on the Internet, I will say go for it and try it out! The process is fun and the result is very rewarding.
