1- I suspect you used the integration package to install for some reason, or possibly you made life hard ;). The normal download has an installer, there is never ever a need to edit a config file.
2- If not mentioned in the Setup Wizard issue, it is something we intend.
3- Maybe discussed in one of the Theme Wizard issues. We also have some other things up in the air in this kind of area.
This was done with installation-profiles a while back.
Generally wizards are considered poor usability by usability experts, so there's no plan to squeeze everything into wizards, but the setup wizard installation-profiles work very nicely as quick starts.
(Thanks though, we agree!)
