[Koha] What if mysql stops being around?

Hi all, These last couple of hours, i've been trying to access different *.mysql.com sites (for my non-Koha work). None of them responding to a http request. I'm not being a fear-monger or crystal gazer here, but I'm dependent on MySQL for several apps that i commercially support, which includes Koha. I wonder just how ready or MySQL dependent are we (Koha users) as a community, just in case, Oracle decides to stop further work on MySQL? I'm aware of efforts like Drizzle. But how are we positioned w.r.t MySQL deps and what could hypothetically could be a possible life after MySQL (if it ever comes to that) -indra
