Basically everyone uses x86 bit numbering. It has the pleasant property that the place value of every bit is always 2^n (or -2^n for a sign bit), and zero-extending a value doesn't change the numbering of its bits.

Sure, it is by far the industry standard. It works much better for handling discrete integers. Once you get into bitfield instructions it is nice to have bit 0 be the "left most bit".

It's a mistake to call it x86 bit numbering, it's way older than that.
