They're a guideline for game balance. If you're full up on capacity and you want to have some feedback technology built into your bodysuit, then it's not a hard rule, and you can talk to your gamemaster about it.
So if you want to have a game where everyone doesn't have 6 levels of Thermal Dampening, Insulation, Nonconductivity, Ruthenium Chameleon Coat, Environtmental Resistance, etc. Then stick to the rules.
I don't think of them so much as optional but bendable.
I wouldn't mind them (I like the concept) if they made any damn sense. Getting a skinlink built into your armor takes the same amount of capacity as getting Nonconductivity Rating 6. Or getting a Feedback System.
And the chameleon coating takes up no capacity.
