@zensaiyuki In the case of browsers, the question seems to have always been not whether to have configuration but who should be configuring these settings.
The standards now say that webdevs have ultimate say whilst browsers provide defaults. The problem though is that the defaults are no longer reasonable, and webdev's final say can't always be trusted for reasons you've described in other toots.
Fairly trivial to fix when I'm not worrying about breaking JS...
@alcinnz it is certainly possible and even easy to write webpages and even web apps that leave browser accessibility settings available and working. it’s an education problem though and if, i, for instance, wrote a guide on how to do it, everything in it would fly in the face currently fashionable practices, which seem to view accessibility as “old fashioned”
