In which way do you want to make use of the support? Are you going to 
change the database definitions and all database accessing code and 
propagate changes to the detail tables for example? Sounds challenging, 
I haven't seen that people doing with mysql yet, but well, never fear 
new steps ;-)

How does that work with our multiple database approach? I think we have 
to support at least MySQL, Sqlite, Postgres and Oracle. Does the MDB2 
layer support all these features? Does that complicate the code?

Honestly, I do not think this is something we just want to push to 
master and go with it from than. I think we should use time to get more 
experienced with it, as these kind of changes show the impact often on 
the longer run.
Can't we have that as an additional database and keep the old MySQL 
implementation as well for the next couple of versions?

Well, you will find lots of systems with old MySQL which either do not 
have InnoDB or InnoDB in version that you do not want to use ;-)
