Colin told me that making Ibuffer the default was contingent upon it
taking less space or consing less.

Ibuffer does use the header-line, but for displaying what filters
(not filter groups) are active.

I recently changed it to work better, especially for relatively
default cases like emacs -nw and Emacs under X with a left-sided
scrollbar and left-sided fringe (before it just used one space char
regardless).  But it seems doomed to lose given unusual settings.  Is
there a straight-forward way to cons up pixel-perfect spacing, say as
a display property ?
