I believe it is more fundamental. I like to think that AV1 entropy coding just becomes ineffective for large values. Large values are dominantly present in high quality photography and in lossless coding. Large values are repeatedly prefix coded and this makes effective adaptation of the statistics difficult for large integers. This is a fundamental difference and not a minor difference in focus.

You mean exponential golomb style, where numbers like 0b110100101 would be encoded as 00000000110100110 (essentially using 2 bits per bit)?
