Comment (by mascguy):

 I've done some initial POC work on this. But it's more involved than just
 a simple update to all of these ports: For example, it appears (?) that
 upstream has potentially combined the `openexr` and `ilmbase` components.
 There are also build changes, including migration to CMake.

 There may also be breaking API changes, but not yet 100% clear on that.
 And some dependent ports may not build with the latest release, but again,
 it's not yet clear.

 None of this is insurmountable. But given all of the changes, it might be
 easier to create new segregated versions. That way existing ports will
 continue to work as-is, and we can migrate them to the new version as time
 allows.

 But I'd really like to hear from Marcus, as perhaps he's already done much
 of the legwork on this. Ditto for his thoughts on the potential approach.
