That's my opinion too, but I was outvoted in another subthread -- see
https://postgr.es/m/20181214144529.wvmjwmy7wxgmgyb3@alvherre.pgsql
Stephen Frost, Andrew Gierth and Andres Freund all voted to put
CONCURRENTLY outside the parens. It seems we now have three votes to
put it *in* the parens (you, Peter Eisentraut, me). I guess more votes
are needed to settle this issue.
My opinion is that if we had had parenthesized options lists back when
CREATE INDEX CONCURRENTLY was invented, we would have put it there.
But we were young and needed the money ...
