It is no demand, but convinient to have many gfci's.
The color codes were: RED: hig voltage as neon signs etc. Yellow: central heating, oil burning boilers etc. Green: computers or other equipment needing controlled shut down. Not sure if this really was in a code, or just commonly used.

Having many is a good idea. Ground fault only turn off one circuit.
