I dug a bit into the history.

`flet's implementation indeed lost its implicit `cl-block' in

  de7e2b36875 Get rid of cl-lexical-let, keeping only lexical-let for
  compatibility.

probably by accident.

OTOH it looks like `cl-labels' never created implicit blocks.  As the
manual describes it as especially useful for recursive local function
bindings, this case is maybe also a bit different.
