Do we need large-scale consensus building on the future of printf-style
statements to introduce a way for critical (stacksize-wise) components
to do without whatever we do about printf being hard on resources?

(And when was this ever about banning stdio in full? AIU this is more
about providing better tools than what is in stdio, or using the good
tools that exist where we don't need full printf).
