Bug reports are a way to measure how well the behavior is approaching correct. You seem to not be satisfied with messenger.com's experience; valid, it seems. It's a large app with bugs. But your point is obscured by the fact that you seem to be poo-pooing one of the few ways that the development team can get feedback on what users actually experience on a day-to-day basis.
chenglou is doing a bit of massaging of the numbers; the claim that there's "only been 10 bugs" isn't quite true. Their code base is 50% ReasonML and 50% JS, and in the ReasonML portion, they've only had 10 bugs - a signification reduction! But they haven't commented on how many bugs are reported in the JS side; we can probably infer that there is many more (since the implication is that there were many more bugs in the old JS code they replaced).
You seem to be frustrated that the messenger.com experience is not up to par and have latched on to the idea that, since the team says they're seeing improvements since introducing ReasonML, that they think they're perfect now. I guarantee you that's not the case.
It sounds like you have some very valid complaints, though, and as a daily user I bet they'd love to hear your feedback. So maybe fill out a bug report with what you just wrote? :)
