Linux layout puts Control where Caps Lock is on the keyboard. I swapped Caps Lock with Control before I got an HHKB, and it made so much more sense. It was more comfortable, practical, and I never accidentally hit it. There's a lot of RAGE about people typing in caps, I never found my eyes straining to read them, although I've heard that typing in caps makes you read slower.
Addressing your question, I could not do away with a function entirely on a keyboard. I guess it all boils down to "Do you use it?". A lot of heat stems from a function issue, such as disabling Windows keys to prevent a full screen game from getting minimized, or having a keyboard without a numpad so you can hold your mouse closer to your keyboard. Honestly if you didn't switch Caps Lock with Control, then I don't really see the point of disabling it, unless you like the inside joke of hating caps lock "Ha Ha! Take that caps lock...I'll never use YOU aga...damnit, I just hit caps to type that", or maybe it's to spite the Caps Lock gods. Or if you accidentally hit it THAT often, that you have to disable it.
Even the minimalist HHKB has an option to turn it on.
edit: Personally speaking, I only use my right pinky when I'm uppercasing letters. The left shift gets it's use from shortcuts in applications, otherwise it just doesn't get used. EVEN WHEN I TYPE THIS I just hold the shift key down and type it out. I guess my right pinky just doesn't get used enough, and can afford to be pinned down when I need to type something in all caps
