One idea was to not display default parameters in the echo area.
So when e.g. char-fold search is t by default then it should not
be indicated in the echo area.

Like case-fold search, char-fold search could be disabled either by
customizing the corresponding variable, or interactively with ‘M-s '’.

AFAIK, a drastic change was not in lax whitespace search per se, but
only in its combination with char-fold search that we could fix now.
