New ISO Multi-Purpose "Shelter" Sign?

So I was scrolling around the ISO 7010 catalog when I came upon this very intriguing sign released just last December.

According to the description, it is supposed to make people be “…aware of the location of a protection shelter”. Of course, the supplementary text is required to distinguish it from other shelters and the like.

Do you think this sign is going to be used considering that it’s newly released and there is not a set standard for a shelter sign for severe weather? What are your thoughts on this newly released standard?
