Everything is subject to criticism and change. That's how life works. There's no point where we stop and say "OK everything is fine now, no need for further change".
That has been true of D&D in the past and it will continue to be true in the future.
Race level limits, alignment languages, lack of class options, homogenous monster alignments, "Fighting Man", lower strength maximums for women, no pictures of BIPOC in the PHB, "mongrel" half-orcs - all of these were criticised and, as a consequence, changed.
Absolutely everything in D&D has been criticised. Lots of it has changed. Any aspect of it may change in the future.
And how many of those were due to moral outrage?
