That's certainly possible in D-I, but it'll take some effort to implement 
nicely. Probably fairly straightforward for preseeded installs using 
partman-auto-raid, but for interactive ones we should really restructure 
the user interface a bit (do setup from a central RAID setup dialog with 
options instead of using a linear series of dialogs).

Do you want to do that in mdadm itself, or should D-I do it?
For consistency mdadm seems more logical.
