I'm all for neatly aligned text, and I appreciate the increased
cosmetic appeal, but surely the fact that this masks semantic
differences is more important.

    The CA in usage 0 is not a trust anchor, but it is in usage 2.

    The chain in usage 2 still requires PKIX validation, be it with
    a dynamically obtained trust anchor.

So PKIX-TA and DANE-TA are each misleading, the first is not a TA,
the second is still PKIX.  Are the acronyms just supposed to be
more memorable than the numbers, or are they supposed to concisely
convey the associated meaning?
