Why is this needed for anything else?  I don't recall that being
discussed in the meeting.

The only reason for "auto-multicol" is to handle the case of "infinite
inline-axis space" in a way that's not super user-hostile.  The naive
behavior *is* extremely user-hostile; it effectively makes the
orthogonal element max-content in the inline axis (requiring the user
to scroll back and forth to read lines of text; we all know how
terrible this is when reading some accidentally-long <pre> text) and,
if there's enough block-axis content, overflowing in the page's
secondary scrolling direction (the one that's annoying to scroll in).
That situation never occurs anywhere except orthogonal flows, because
the inline axis space is always finite when all the writing modes
match.
