Thanks for explaining the logic behind the current implementation.

Unfortunately, I think this makes a valid use case
impossible. Specifically, I like to be able to set an image width
explicitly with #+attr_org (or some other attr_ for the corresponding
export) and fall back to the actual image width when this isn't
specified. This includes the ability to use the actual image width in an
org buffer, but an explicitly-set image width for export. For example,
for my blog I often have attr_html set, but I want the image to use its
actual width when displayed in org. I don't see how this is possible
with the current implementation. But, it works naturally with the
implementation I have in mind (IIRC this is how it previously worked,
but I could be mistaken).

I do understand the desire to avoid specifying a whole bunch of
redundant attr_ settings, but I don't think it should make fine-tuned
use cases like the one above impossible. I also find the current
implementation a bit counterintuitive, if less verbose. Maybe a solution
to accomplish all goals would be to add an #+attr_fallback (or
attr_default, attr_any, attr_all, etc.) that is used for any backend
unless a specific setting is made for that backend.
