I feel skeptical when a feature needs new functionality in the core files of
Browser. Why does this need to be here rather than at the point of use, using
BrowserList and BrowserIterator?

This is a very good point. I had no knowledge of BrowserList and
BrowserIterator. I have removed all the changes in browser_finder.* and followed
your instruction. Thanks.
