Wasn't part of the reason that nobody was maintaining it was because it was meant to be a way to start a Perl script faster that turned out to be much slower? So even when you didn't run into a bug, it was slow enough to be of little value. If somebody wanted it as a way to hide source code, then the existence of B::Deparse likely makes it at least much less than foolproof.
So I thought it was an interesting idea that turned out to be rather useless and hard to maintain so it was no surprise that it wasn't maintained. But I only ever paid peripheral attention to it.
