I didn't intend to create that impression. On the contrary. I don't do a lot of ABW printing (prefer QTR), but I wouldn't consider printing with ABW without having a QTR-generated profile, either for a preserve numbers soft-proof or for a regular soft proof and conversion to the profile at print time (noting my earlier comments about shadow detail). I don't find ABW to be all that consistent in its linearity from printer to printer, and so the QTR profiles are essential in my view in order to see what's happening and to be able to control it predictably. They may not be essential to people who, through a process of trial and error and much experience, have a very good feel for how their printer will render an image. But it takes time to get to that point, and in my view, a soft-proof can still help, even when you do.
The comment about relevance was in relation to Photoshop, and why it doesn't display the greyscale profiles created by QTR-Create-ICC.exe in the printer profile list box. This is at the stage when you're going to print, not in the soft-proofing dialog. Photoshop doesn't consider them relevant (pardon the anthropomorphism) for a RGB printer. It will show the RGB versions that QTR-Create-ICC-RGB.exe creates.
Waste can't be avoided, but I prefer to minimise it.

I was more addressing the brief earlier mention of using the profiles without printing via QTR as perhaps not being relevant here...

As to less 'waste' - well I prefer to see that as part of the ongoing costs of honing my craft - YMMV ;-)
