IMHO, an equivalent of :environment for images is
\includegraphics or \includesvg.

As I said above, I feel that :environment term will be overloaded then.
What about :wrap?

Do we know in advance which environments support \caption and which not?
I feel that we may handle this programmatically without creating an array
of almost-identical attributes.
