If DevTools is crashing, then I believe that DevTools has the problem and not Vanadium. Even if an old Vanadium is "speaking a broken protocol," a high-quality DevTools would cope with that. Since it crashes, it's not coping with that. I should be able to "fuzz" DevTools without it crashing and my "fuzzer" could be an old Vanadium, a new Vanadium, or /dev/urandom.
Thank you for considering the situation. I wasn't complaining about Vanadium nor reporting an issue with it. I was asking if it could be used with DevTools. The answer is "yes." And that's great! 😀
