Print Booklet is a convenience feature for output to office-type printers, not a full-blown professional imposition engine.
Calling it a convenience feature is not helping it, as it is more of an inconvenience now. I was not asking for a 'full-blown professional imposition engine', but merely for the Adobe to make all considerations when making new features available. This 'convenience feature' is used much more extensively than you may know. My request is not an unreasonable one.
