Thanks for a friendly conversation, but I would have to say that
Taylor's "we know we end up having to support both, and we will do
so" is way underestimates the cost to do so.  And I hope that an
actively maintained and vendor supported commercial platform would
bear the burden of the major part of that cost themselves, when it
becomes necessary to do such a dual support.

Thanks.
