Ah, interesting !
For me, the fact that you have to despecialize every slash inside a regex string is a use case big enough to justify raw strings.
I will happily admit that I'm biased by the fact that I see my students struggling to write the correct string to feed Pattern.compile or String.split every year.

But maybe a specific syntax for regex that create a Pattern using a condy is a better idea ?
