Now, I'll admit, looking at the contents of your browser cache isn't something that you normally want or need to do, so it really doesn't matter how things are organized. But what possible benefit would there be to this new layout (versus the old way tof doing it)? It seems like an odd design decision.

Filesystem efficiency. General-purpose fiesystems don't handle directories with tens or hundreds of thousands of files all that well. There are special-purpose filsystems that do (reiserfs among them), but those are not available everywhere.

Many other programs use a similar arrangement too. Git has only a single level of two digits, while Squid uses a similar arrangement to Firefox.
