It required me to do nothing to the setup otherwise. The RD is more than capable of wrapping of the "extra" tooth of range.
Much thanks - based on your info I was putting together a shopping list for the SRAM cassette, Shimano spacer, Hunt XDR adaptor and then started searching around for the 42 or 44 tooth front chainring and ran into the Wolf Tooth GRX chainring options. So now thinking I'll first try just replacing the front chainring with their GRX 44 or 46 tooth chainring and then see how that goes.
