Nothing about timekeeping is simple, with or without this change. Not only do some regions already not observe DST (even within the same state/region); some switch to/from DST at different times of year (and this date changes from year to year). For a timekeeping library (which likely uses a system-level source of data / the IANA tz database) this shouldn't have any effect.
