[cssom] computed style for flex-basis (as in getComputedStyle())

Hi there!

I was looking at https://drafts.csswg.org/cssom/#resolved-value today.
I was wondering if flex-basis should be added to the list of resolved
values? In many ways it is similar to width/height. I'm not
necessarily arguing for its inclusion, was just wondering if that was
considered.

Thanks!
