Yes, you're right.

Not without making Emacs startup way more complicated than it is.

Since there appears to be no way to really solve this problem, I suggest
simply mitigating it, by adding an optional argument to `load-theme'
skips the confirmation.  Users who wish to call `load-theme' in the init
file can then use this argument.

If no one has a better suggestion, I will go ahead and implement this,
and update the relevant docstrings to mention this pitfall.
