I'm perfectly fine if a desktop implementer decides that they are not 
going to send low memory events.
For me, the purpose of getting the event in the specs is to promote its 
use, and ensure that the HTML
spec for mobile and desktop stays in sync.

It's clearly a useful event for mobile; even if desktop vendors decide 
not to fire events, it'd be good
to see it in the specs.
