If they refuse to contemplate suggestions as to how to write more
portable SQL queries that would work with databases other than MySQL,
then I don't know what constructive discussion there can be about this.

Why, when the MySQLisms in questions are divergences from the SQL
standards, and the issue seems to bite all the other databases in more
or less the same way?

It doesn't seem to me that the answer to "Drupal developers refuse to
consider writing portable SQL" is to try to impose MySQL's divergences
from SQL onto all the *other* DBMSes.
