I implemented the simplest form of the PR -- just encoding the LR value mod MaxEntries and reconstructing the value in the decoder.  It shows a 148 byte or .26% wire savings encoding a browser session with a few hundred requests.  It took ~20 lines of code in the encoder and decoder to make it work, including handling a new error case (encoded LR > MaxEntries * 2 + 1).
