It's an interesting point. XProc grew a fair bit of additional
"binary" support late in the day with p:data and the various
content-type options.

Given that you can load a PNG, it seems odd that you can't store it.

I suppose the simplest way to fix this problem would be to take
advantage of the media-type serialization option. It would (I think)
be conformant for an implementation to accept:

  <p:store content-type="image/png" href="my.png">
    <p:input port="source">
      <p:inline>
        <c:data content-type="image/png">BASE64ENCODEDDATA</c:data>
      </p:inline>
    </p:input>
  </p:store>

and write the decoded PNG data to my.png.

Does anyone think that's not conformant?
