I don't see who would have the authority to do this.  I can, of  
course, add a s'yag for myself, because I think I personally am at  
risk (e.g., I used to have a sink faucet in which it was easy to turn  
on the hot water by accident, so I would turn off the hot water  
cut-off below the sink for Shabbos).  Perhaps if I ask a shaila, a  
posek might recommend to me a s'yag, although even there if it is not  
required, I don't see how he would have the authority to pasken I must  
do so.  (I.e., it would be only as binding as any other eitzah tova  
from a posek- I leave it as an exercise to the reader as to how  
binding that is.)

But a gezeirah that would be binding on the klal, even if they never asked?
