Sometimes you don't see problems until more people are using a thing.

I reported a bot issue with VisualEditor (that is, bot flags not being passed to edits done through it with bots) that they somehow didn't come across in prior testing (maybe they hadn't considered internal testing with bot flags, and it may have been unlikely brand new public wikis would have users with bot flags, especially ones editing the wiki directly (I was doing it logged into my bot account because I needed to use a Dev Wiki script and had to rearrange my bot's user JS to get it to work)).
