I don't have strong feelings about "hsk", but I don't think an option to "ols" works as an alternative, since it's not a case of OLS. We consolidated the FGLS variants for AR(1) estimation, which used to have their own commands at one time, under a common "ar1" command, but I don't see a "natural" place to consolidate hsk.
