I *mostly* agree. I guess it depends on what you call optional I guess.
Some things are needed to build and test ant at the moment (ie junit + xml
parser) while others will become more important in future (ie
xalan+stylebook or cocoon2 when we auto-gen documentation). Asking people
to jump aroun all over the place to get it to build is not something I want
to see.

For other things that are not needed for building and/or not popular enough
(ie jar for ftp task) would be excluded. When a jar is needed to build ant
or is popular enough I think we should chuck it in.

but they are ;) and/or will be in future.

I agree for other non-essentials (ie regexp/ftp/other jars) but not for
necessary components.

Unfortunately this is a requirement because ant is still in active
developement. It would be unacceptable for other projects to stop building
because of a change in ant. It would also be unacceptable if ant stopped
being able to be built and tested if stylebook/xalan/junit changed.

I agree for "optional" components.
