PEAR doesn't have a common prefix, which leads to some problems. (To be
fair, though, PEAR2 will introduce a common prefix and namespace, btw.)
If you have a lot of libraries with different prefixes in library/, yes,
setting the autoloader to act as a fallback autoloader is a good idea.
However, if the list is finite, it's a good idea to set the namespaces
explicitly, as they will match faster and more accurately... which you
show below:

That's good advice... and I'm surprised that I didn't make the flag
default to this. I'll file an issue in the tracker to rectify this
situation, as we wanted it defaulting to no suppression. (When you're
not using it as a fallback autoloader, there's little to no need for
suppression.)
