The only reason the groups mentioned in the canons were received through chrismation- aside from the fact they still retained the Orthodox form is that their clergy were only once removed from Orthodoxy. As St. Basil the Great says, the schismatic/heretical clergy that have broken from the Church effectively become laymen. Only an ORTHODOX layman can act in an emergency baptism and if the individual survives, the bishop has the option to baptize him or receive him by chrismation. The Church knows no such custom with heterodox twice removed, all those sects mentioned in the canons were only once removed having schismed directly from us. What is practised today is simply bad baptismal theology influenced by ecumenism with the Latins who claim anyone even atheists and muslims can officiate in baptism.
Therefore it can be argued that there is no apostolic succession outside of the Church. Secondly if apostolic succession is not found outside of the Church nor valid baptism why do the Church councils and cannons allow for the reception of some heretics, such as Arians, by Chrismation?
Todays practise is based on policy on the archdiocese level determined by how friendly the heterodox are to us, not to mention foregoing baptism is convenient.
Thus places such as Athos which sometimes insist on baptizing even converts are well within Orthodox praxis.
