Judging by the Wikipedia article[1], it sounds like at least DB2 and MySQL/MariaDB are purposely striving for conformance. When I worked with DB2 a few years back I preferred to use their standard-conforming PL stuff (as opposed to their be-more-like-Oracle PL/SQL mode), and I always hoped that PostgreSQL would eventually understand the same syntax; admittedly, anyone who has ever worked on large applications that support multiple RDBMSs knows that there's more than just surface syntax to worry about, but it still seems like a pretty solid plan to conform to the standard that's in our name, so +1 from me on the general direction (I didn't look at the patch).
