In #halakhah there never was a mandatory 6 hour wait time between eating milk and meat. That idea is a more recent (1500's) chumra חומרה (stringency.) People of course may follow this, but they should also know the history. Ashkenazi Orthodox insist on this waiting time as binding. Other Jews disagree.
