No, it's not fine.
It fixes the WRONG END of the inconsistency.
It's like saying "Ooh, these people have two legs and those
people have one leg, the easiest thing to do is to cut one
leg off those who have too."
It harms readability in the eyes of a lot of people.
Like I said, you would have to pay me big money to read
code written in that style.
It certainly breaks *my* pretty-printer and editor.
Michael Turner is at perfect liberty to add any feature he
likes to his copy of Erlang. He is at liberty to offer it
to other people.

And why do you think I don't use Clojure?
