To be perfectly clear (which the title is not), this refers to supercooled water, that is liquid water below 0 degrees C. Which you don't really find outside of laboratories.
If you're framing it as "...worth spending..." then you can do the sums, if you like.
e.g. if you have a 1 in 1000 event that is 24h without electricity (once every 2 or 3 years?) You'd normally spend 30 a day on electricity, plus a cost for the convenience of not having it happen, lifetime of what 10-20 years, so multiply that up.
And if you can quantify the other benefits (using the variable daily rates, etc) then you get a better estimate.
So your thought is valid (in a quantitative / utilitarian kinda way), but not new. It looks to me like we are at or approaching the point where for people who put high value on convenience, it is worth it. For those who don't, it isn't.
