What happens when you customize minibuffer-follows-selected-frame
to a third possible value that is not nil and not t.  From docs:

   Any other value means the minibuffer will move onto another frame, but
   only when the user starts using a minibuffer there.

I guess this variable is not intended to do what you expected.

But AFAIU, what you need is only to use with-current-buffer
wrapped around the interactive spec?  There is no need
to select another window/frame while reading from the minibuffer?

I don't like creating wrapper commands too, but it seems there is no
better way, at least no one proposed anything better.
