I don't think we can do that by default.  We need some evidence that
this is the intent.

Exactly.  And doing so is a very wide-spread paradigm in Emacs.  Which
is one reason why enable-recursive-minibuffers is not turned on by
default, and should be considered an advanced feature for users who
"know what they are doing" and are ready to sustain the consequences.

Perhaps.  But I'd like to hear concrete ideas for such experiments
before I have an opinion on their value.
