Yep, the explanation is very easy:

There is already a context, including a legacy service. Unfortunately, the
best way to get at this context from an *ImageJ 1.x plugin* that I could
come up with is:
import org.scijava.Context;
...
final Context context = (Context)
IJ.runPlugIn(Context.class.getName(), "");
final ImgOpener opener = new ImgOpener(context);
(There is no way to make that more convenient without letting SCIFIO
depend on ImageJ 1.x, which is of course a big no-no).
Of course, you could also turn your plugin into an ImageJ2 plugin -- which
is handled properly in Fiji thanks to Fiji Just Being ImageJ2 -- and then
it would become as easy as:
@Parameter
private IOService io;
...
// use the IOService (which lets SCIFIO handle
// things) to open your dataset
Ciao,
Johannes
