No, you're only considering a single case, that of low level hiss.
That's not the only case where you have [audible] audio content under
-90dB.

It's 96dB, and that's only using the most simpleminded measure of
dynamic range.  In fact, 16 bits has closer to 130dB of usable signal
range (look at the frequency plots).  I'm happy to demostrate if you
don't believe me.

Setting a hard limit that throws away potentially 1/3 of the dymanic
range is not really a good idea.
