The amount of space saved is near insignificant.

I'm sure there are many modules where the savings would be neglible, but POD makes up 1/2 of CGI.pm and LWP::UserAgent. If that were true for the majority of modules out there, that's a very significant savings, especially if you're playing in enviroments where space is at a premium (embeded systems, flash cards, install CDs).

That said, you can save far more space by whittling down a lot of the excess baggage in core distribution than by stripping POD (as touched on in this p5p thread); although doing both should make for a really minimalist Perl install! ;)
