I think the bar should be pretty high before we add a third way to write
function application to base. How common is this? Common among whom? Why
can't the existing idioms of (.) and ($) work just as well?

I guardedly agree with Dave Menendez.  There are a very limited number of convenient 1-character operators available, and I'm not certain that function application should take up 3 of them.

On the other hand, this is a common enough idiom to have emerged in both diagrams and lens at least.
