I was suggesting that there may be benefit to digitizing at 24 bits when

a sharp FIR high-pass at 18 Hz and you still have plenty of bits of signal
left if you are lucky.

So the situation you're describing is something like this: the analog
signal being input to the ADC has a relatively low analog SNR. Correct?

In that case I really don't see why digitizing at a higher depth buys
you anything.

It doesn't with any modern DAW software. Nothing does internal
processing at 16 bits any more, and haven't for many years. But if
recording 12 bits of data at a 24bit sample size makes people happy,
then as they say, it won't hurt at least.
