Hab modules/WayPoint stations should be able to load balance with components just like the universal hoses do. That is, if you install more then the required components it's going to use the extras to reduce strain on the others. That forces the player to do a trade-off between spending extra components to keep the thing working longer vs saving them for another module. For some things like fuses you might want to install all three in WayPoint stations just so they will last quite long, while for hab modules you decide that since you are around your hab a lot you can spend the extra time checking up on them.
