The problem with premature abstraction is that it becomes difficult or impossible to reabstract since you're not looking at the root issue anymore but rather attempting to unroll a failed abstraction. Often by the time the abstraction is such a failure that it needs to be rewritten, it's evolved into its own system with a menagerie of hacks latched on to let it live another day. You're not going to just come up with a regeneralization because more often than not it's not generalizing anything anymore. Seems a bit much to "throw up in your mouth a little". Premature abstraction and the high cost of indirection are responsible for some of the hardest problems in software and you don't offer a solution beyond "try anyways".
