Why ignore the component xml file means doesn't work, in practice, the
component.xml file
is impossible for users to edit it manually, you are expert ;-) , you
know about the virtual component
model, but most of users don't know and what it is for.
I admit that it really is a bug for only handling one wb-resource
mapping, I appreciate if you can
create a jira or let me know when you find a bug or something doesn't work.

I have not investigated WTP code deep enough so I really don't find any
guides that told me
I must use Virtual Component to look for all related resources in module
factory, if you are familiar
with it, you can speak up or create a jira, rather than so easy to be
annoyed ;-) .

I tried to use ComponentDeployable as ESB module delegate, so far, it
works fine, it might work like
what you said, using virtual component to get which resources will be
deployed, not sure if it would
absolutely work for ESB deployment since I can't read all its code, I
will do some more tests.
If we change it to use ComponentDeployable as module delegate, the old
component xml file doesn't
work, so we have think about support of old esb project.
