We absolutely will continue to support CFN template format, because we have
existing users who rely on this feature.
At some future point the there may be an internal conversion from
cfn->native/dsl/hot format, but atm our internal implementation is highly
coupled to the cfn format abstractions, so we can't (and won't) just
suddenly switch to something completely different - maintaining our
exisiting functionality is very important.

The simple answer is it's way too much effort to natively support every
single template format anyone could possibly want.
Hence the summit discussion focussing on definining a superset of logical
abstractions/concepts which can be added to our existing internal model,
such that top-level translation from the various formats should be
As Thomas has pointed out, this translation can (and IMO should) be
something that gets started outside the Heat project, or at least outside
of our main codebase, e.g via tools/foo2heat.py standalone tools.
