Even as a former Cure 1 enjoyer, I'm not convinced that's actually true at the level cap anymore. If 0.5 seconds is actually a difference, We can apply far more healing far more rapidly through Lilies/Tetra/Benison/Bene.
A frankly, with 20 second Lilies, you're getting lilies faster than mechanics happen nowadays
Cure 1 has 100% had it's day and for the good of our button bloat, should make way for something else that is more consistently useful and interesting.
