In an ideal world, I agree.  But suppose you can't because a legacy
architechture that you're migrating from has that /24 full of
customer-facing addresses?

Or suppose you use GLBP and need to add an n+1 th router to the
forwarding path and there's no free addressing left (see above
constraint).  This feature lets you stack a few cheaper boxes up until
you get budget cleared for an upgrade.

As was said elsewhere in the thread, it's not really pretty, but it
can be quite useful.
