Thanks for the feedback! Our primary use-case when deciding on it was to flag these up in a code-review situation, to prevent malicious content being submitted in merge requests to unsuspecting projects. We found this made it stand out enough to the reviewer when performing code reviews. I also try to not be too quick to add new alerts or sections to the GUI as we sometimes get criticised for having too much clutter D:

GitHub by comparison went down the alert banner route, from what I can see. I'm not opposed to adding something to that effect as well though - especially for inexperienced reviewers, it would be nice to include some more information about the potential exploit. That could be something we revisit when we add the homoglyph highlighting.
