I wrote 90% of a strict URI parser over a year ago, I know that RFC way better than I'd like to. I stopped at 90% after discovering the reason why my fuzzer was generating test failures: the ABNF is wrong. I believe it was around the query portion of URI segmentation, where two potential interpretations shared the same order of precedence and there was no rule on the order of execution. I'll finish that project one day... because I still don't know how scared I should be about that sort of ambiguity making it through more than one ABNF parser.
