Most likely you did this because you felt all the other ones are too complicated.
But the reason the “enterprise” ones are so complicated is to serve their enterprise customers, who need “just this one feature” so they can use it. But those customers pay the bills.
So basically you have to choose complexity and profit or simplicity and less (or no) profit.
Good luck! But make sure you’re ready to make that choice.
Almost none of the complexity comes from what configuration options I've registered ahead of time. It comes almost entirely from, "Well darn, this code depends on this completely unrelated part of the project. I wish it didn't, but now the build tool either needs to sometimes fail to rebuild something correctly, or it needs to build way too much to run quickly."
This runs counter to how most people think of things like Bazel which are tools you should only reach for when the situation has already grown out of control.
