Thanks for the explanation.

Strictly speaking, the package has no "dependency" on python-mysqldb, only
a "suggests". It can be used with other database drivers as well.

While I understand your reasoning, I believe that this change must happen
at the upstream level first. Debian has no similar restriction and I thus
don't see the need to diverge from upstream on this specific point.

Jeremy, alternatively, you could possibly create a
python-pymsql-as-mysqldb that would "Provide: python-mysqldb" and would
contain the corresponding Python package but built on top of
python-pymysql (and would conflict with python-mysqldb). That might be
something upstreamable in pymysql or in the Debian package of
python-pymysql.

I see that many Openstack packages in Debian depend on both
python-mysqldb and python-pymysql. I guess in Ubuntu they depend only in
python-pymysql? Is the difference explained by this Django patch only?
