I guess I missed a beat; why can't we do the latter? Is it because of
the way we describe operations? IMO this operation should be on an
equal footing with adding resources and we should have a uniform means

I think what you are looking for is being addressed as part of different issue.

We had discussion about it few months back.

The proposed behavior is described here https://gist.github.com/ctomc/91055a6f4e7502dcd130

The first part about collections operations is already done the extended write/read-attribute syntax not yet.
Jira for it https://issues.jboss.org/browse/WFCORE-460

Is this what you are aiming for?

as :write-attributes operation we are talking about is different thing, just allowing us to atomically update more than

one attribute. The extended manipulation syntax would also apply to this.
