Zane,
I am working the defect you had filed, which would clean up backup stack
along with the resources, templates and other data.

However, I simply don't want to delete the templates for the same reason
as we don't hard-delete the stack. Anyone who deploys a stack and
updates it over time would want to view the the updates in the templates
for debugging or auditing reasons. It is not fair to assume that every
user has a VCS with him to store the templates. It is kind of
inconvenience for me to not have the ability to view my updates in
templates.

We need not go as far as git or any VCS. Any library which can do a diff
and patch of text files can be used, like the google-diff-match-patch.
