That definitely didn't work. Features we wanted to use that were standardized could not be used. Even after the browser got updated, we couldn't use them because lots of people used the old browser.
Browser incompatibility was used to lock entire enterprises into using only Internet Explorer. Badges did nothing to help.
The only thing it seemed to do was let you know what browser the developer/s were using.
If you happened to have multiple browsers it was possibly of some benefit if you could switch to that browser.
Enterprises still lock users to one browser if possible for security & maintenance reasons. I do see multiple browsers allowed for certain individuals to support older software.
