I personally use it because I like to quickly tell if I am doing an
operation on a string or array, it is eye candy and makes a lot of
sense. I think if anything the two syntaxes should be decoupled
instead.

have been working with a code base where I have not seen this syntax
used.
I have asked fellow developers around in my community today and they
have no strong opinion on either, but do like the distinction between.

For me personally it is a huge -1, if anything I would like the
string[] syntax decoupled.
