Hmm, so the above change makes Grid chapter 4.4 obsolete, right?

If not, please describe in detail in which situations the spec text
in 4.4 applies.

Before the above change it did apply when the track min-sizing
function is 'auto' (e.g. "grid-template-columns: auto") for items
with a computed value of 'auto' for 'min-width'/'min-height'
in the relevant axis.  But now, the above spec text says that
the "min-content contribution"[1] should be used instead in this
situation.  I'm not aware of any other situations where 4.4 was
relevant so AFAICT it can be removed now.
