 Although mildly troubling the simple check; there is actually no break
 from WP core as it doesn't support SVG.

 I patched my plugin to work around the code by faking
 `application/svg+xml` mime type and then overriding later on.


 Much as it was a little PITA to change code (it always is), SVG upload is
 separate from core. AFAIK the objection that stands is that it's a
 security risk, so I'm not sure adding things into core to keep a small
 number of plugins functional rather than update those plugins should be
 such a concern.

 It would be lovely to have all upload types implemented as plugins to
 core, so that passing width and height information, metadata, parsing etc
 becomes easier to support for core and plugin authors augmenting file-
 types more stringent checks etc.

 What would also be lovely although I didn't see it here is if the media
 templates were extensible as currently to work around display issues we
 are doing some... interesting things with output buffering.
