Output or input code density? :-P

IBM's decision to reserve 384 KiB for BIOS and text/graphics buffer mapping be damned!

I heard they're optimizing for speed now.

Yes, you should strip unused parts. Think about TSRs. DOS functions Int21.31 or Int27, as utilized by most TSRs. These are stupid because a majority of TSRs don't need a PSP while installed. Most people don't care to relocate their TSR code in a way to free up all installation code either. Bonus spite if they don't even free their environment. (Besides, memory fragmentation.)
