Absolutely. Sites of all sizes win with memory usage optimizations... 
I'm all for it. While I still maintain split mode is a bit too extreme 
(and presents some complications beyond it's quite impressive RAM usage 
numbers) - I think it hints towards what's important here. Drupal loads 
too much code into RAM per-request.

There are lots of ways to cut this down.. (long help text removed 
.module files, libraries / helper functions moved to .incs, etc - locale 
has already done some of this, but clearly has work still to do).

I was merely pointing out that hitting PHP's 8M limit is not at all 
uncommon, and not the end of the world.
