it depends on the application and the tools.

hmm. again, i'd say it probably depends. if you've looked at the
ServletToolboxManager (which extends XMLToolboxManager), you'll see it
extends the toolbox.xml format to support a "scope" element that
allows you to put singleton-ish tools in the application scope and
thus only be instantiated once.
if it suits your application's purposes, then adding a "singleton"
parameter shouldn't be too hard and could be quite useful.
