It's a potential Heisenbug for (some of) your javascript code. Sometimes things work on some machines and sometimes it doesn't. Unless you have the cert-chain misconfig in your brain-cache you'd probably spend hours debugging confusing bug reports from customers that you fail to reproduce reliably. So it's not just harder to debug, it causes bugs (and indirectly bug-reports you'll need to investigate).
