I don't know that has been updated either. It seems to me
that some of my comments are not addressed. (Here I mean
the exception type) I will mention that.

It seems to me that FP8 to FP4 convert modrm is fixed, it is a clear
bug in documentation, while FP8 to FP6 still remaining a
questionmark to me.

Exactly, AVX10_V1_AUX and AVX10_V2_AUX will be independent bits, just like
most of those AVX512 stuffs. They might be included into a AVX10 version in
future. AVX10_V1_AUX already did that for AVX10.2.

And as I mentioned before, I am not a big fan of that naming since it carries
no actual meaning to me and might cause confusion on numbers, just like this
scenario.
