SEQUENCE keyword is option on GRANT

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/17/sql-grant.html
Description:

The documentation indicates that they keyword SEQUENCE must precede the
sequence_name in a GRANT, but in my experience it is optional:

colin(at)adinkra:~$ psql
psql (17.4 (Debian 17.4-1.pgdg120+2))
Type "help" for help.

colin(at)[local]:colin=> create sequence x;
CREATE SEQUENCE
colin(at)[local]:colin=> grant select on x to public; -- should fail but
works
GRANT
colin(at)[local]:colin=> grant usage on sequence x to public; -- works as
expected
GRANT
colin(at)[local]:colin=> rollback;
ROLLBACK
colin(at)[local]:colin=>

I'm not sure how intentional this is, and whether or not this is mandated by
the SQL standard.
