For me it means I can grind the bugger thinner . Thinner at the spine cuts better too .
e.g. I have a Kizer Feist :
Reverse Tanto 70 mm edge length.
3V
I took the spine thickness from 3mm to 1.5mm and thinner behind the edge while I was at it .
Green Micarta but looks like coarse Burlap (plenty nice though) .
She makes me smile . . . now . . .
Another example , that I had in pocket today :
Spyderco Delica
HAP 40 clad with SUS 410 (I'm telling my self that since this is clad it is tougher; at least in the body of the blade) .
are you ready ?
you're not ready . I'll give you a few minutes to prepare mentally . . . .
It was 2.45 mm at the spine ; it is now 1.25 mm ! Wharncliffe too . 66mm edge length .
I have seven or eight Delicas and this is the only one I have thinned like this .
I've had this thinned HAP 40 for a little over six years .
Some how it still pleases me .
Full disclosure before you tell me it can't possibly have much SUS410 left (and you'd be right); I thinned it by cutting away all the blade from the bottom of the thumb opening hole upward .
Blade width 12.5 mm .
And yes It is now waved. Dambed dangerous knife when clipped to pocket , it'll open even when all you meant to do was take the knife out of your pocket to switch pants. I tend to carry it in bottom of pocket or in a slip .

. . . oh you think that's crazy and over doing things ; I could mention the Spyderco Centofante 3 that I full flat ground ; took off all of that supposed "magic" hollow grind . . . but that is only VG10 and another story for some other time.
