My reasoning is that this will provide you support of your shadow exposure without materially affecting the highlight placement. The compensating effect of minimal agitation in Pyrocat would then keep the development times in a manageable perspective.
If you will check the two images that I have posted in the technical gallery, you can see the benefit of using this technique.
