I'm curious because it's the flip side of the grid typesetting I was
learning about earlier this week. I have no special insights, here...

I think it allows it to become bigger by the same factor.

um, no? :)
I just stumbled across it in core-spa, and empirically determined that it
would give a bit of variability to the interline spacing, which is what
the original poster asked for.
I *think* it's a multiple of \openlineheight by which the interline space
can vary +/-. So the factor cited above seems like it can cause a
variance of up to 16% in line spacing. (And I can imagine Hans is biting
his tongue on this because this big variance can cause a huge difference
in the colour of the text block. :)

Anyway, addressing the original poster's requirements, allowing *no*
stretch in the inter-paragraph spacing (whitespace) makes it hard for the
interline space to handle the whole job of reaching the text block on its
own. I'd suggest looking at the definition of \defineblank and how small/
medium/big are defined in order to get a better balance. In the following
example (modified from the wiki), the spacing adjustment is a lot less
strained if I do \setupwhitespace[big] instead of 12pt.
