Canonically, there is one statement to dispute that the idea was to have a "young attractive woman"; Meeghat said she had been waiting all her life. Not all her adult life. This suggests that, like the Dalai Lama, the greeter of the Lord is to be picked at a very early age. Before it would be known if she would be pretty as an adult, and performing duties while still too young to be atractive to any but a very despicable man. Generally, in such circumstances, a preist/preistess is supposed to hold their position not just from childhood on, but then also into later years. If this society operates the same way, there would only be a small time frame in which the attendant would be young and attractive.
