I would go for a) continue to use ~/.kde4 for KDE 4 applications. This option
keeps .kde for KDE3 apps data that a lot of people will have to use for some
time and for backuping in case users want to go back to KDE 3. Some people
will say here downgrades are not supported, but we all know the change from
KDE 3 to 4 won't please to everybody and it is easy keep on the safe side and do
not mess with people's data. I do not fully see KDE 4 as major upgrade of KDE
3, it is different in a lot of ways...
What could be done here is when users log first time in KDE 4 get some dialog
telling then "hey welcome to KDE 4, your settings are not migrated because X
and Y, you have this migration guide|program from migrating then"...

The option of start a migrating program instead of this warning dialog, also
works for me, but: i do not volunteer for doing or testing it and i still think 
even in this case, it is better keeping .kde4 and not moving to .kde.
