Let-binding enable-recursive-minibuffers temporarily to t was necessary
to fix bug#17272/bug#19064.
So when the minibuffer is already activated, and a minibuffer command
wants to ask a question, displaying another recursive minibuffer with
such question should override the value of enable-recursive-minibuffers.
But you found the problem that is a side-effect of this fix.
The problem is that currently it's impossible for a command
to override enable-recursive-minibuffers only for its own use,
while keeping it disabled for more recursive minibuffer calls.
Maybe enable-recursive-minibuffers should support a numeric value
that is decremented in every recursive minibuffer calls
until reaching zero value that disables more recursive calls?
Then a command that needs to use the recursive minibuffer
could let-bind enable-recursive-minibuffers to 1,
allowing this only for own use, while it will be 0
in more recursive calls.
