I can't say I like it.  Sure, I can see the appeal from a "quick and cheap" standpoint, but the edges of those things are like razor blades more often than not. If they were used, I'd be expecting them to be pretty tightly bunched to preclude the pulling in of additional circuits.

What type of cables? What type of building?
Which option in Table 4A1 would it satisfy? I can't really see it being classed as anything other than 'support wire'.

Some of these bands do have very sharp edges. The way the bands are cut/slit tends to create a small radius on the edge with the sharp edge at angle to the plane of the band.  One way of mitigating the sharp edge is to use the band so that these point outward rather than inward.  You can normally tell by inspection.  Also avoid overly tight clamping.  I have seen T&E outer sheath used as a grommet on the edges of such bands but I imagine its quite hard to get it to stay in place.
