That doesn't mean you get 32 valid bits. Most probably you get 24 and
8 zeros, and if you really get 32 the lower 10 or so are completely
useless. You are confusing the format (a 32 bit integer) and the 
actual content (most likely 24 bits).

There is no debate about this, except maybe among the ignorant.

It is perfectly possible to make a 32 bit converter clip. It will
do so at exactly the same gain settings as a 24 or 16 bit interface.

would at the same gain setting also be ruined when using 32 bits.
Just leave enough headroom by using conservative levels. This will
NOT affect your  S/N ratio which is entirely determined by the
analog circuits if you convert to 24 (or even 16) bits.

You can do exactly the same with 24 bits.

There is no such CPU hit.
