RET_SYS was used for commands failing due to internal or environmental errors, but not really systematically. The difference to RET_FAIL is how dispatch() treats them: RET_SYS got logged, and cost no BTUs. More specific logging is possible at the point of failure than in dispatch(). Make sure that's done for all failures that used to return RET_SYS. The change in BTU charging affects commands consider, offer, repay, trade failing due to internal errors. It also affects deity commands reload and turn (irrelevant because deities get unlimited BTUs), and commands apropos, info and motd (irrelevant because they cost no BTUs).
