I agree this is confusing. Unfortunately we don't have a common name
that describes both MariaDB and MySQL. "MySQL-like" is perhaps the best
we can do. The package name would be default-<something>-client. What do
you suggest that <something> should be?

It is a completely separate package that conflicts with the MySQL
packages as appropriate. Packages that need a mysql-like db should
depend on "default-mysql-server | virtual-mysql-server". In other words,
this already works from the MySQL/MariaDB packaging end.

I agree with you, but the release team have made their decision against
our wishes. There's no point arguing with us. We know.

Agreed, but they'll probably all be "wontfix"ed, since the release team
have made their decision. Perhaps I should create a bug entitled
"Consequences of removing MySQL from testing", "wontfix" that and dupe
everything to it.

This does not exist, and currently nobody has the time to work on this.
I believe MySQL->MariaDB works right now, but the reverse direction
certainly doesn't. Users should take backups before upgrading.

I see your point. Unfortunately it's more complicated than that
(expectations of compatibility, etc). I don't expect any changes on this
Technically detailed proposals for changes are welcome on the
pkg-mysql-maint list. Then we can go into the pros and cons of those
proposals and make a decision. Right now though, there are no plans.
