Ya know, I have school age kids. To be honest, the easier way to spell names helps kids out. Otherwise, they are constantly, their whole life either correcting people or having their name misspelled.
My sister is Wendi and she gets irritated even as an adult because she has to respell her name for everyone and gets things sent to her with Wendy even from people that she knows well which makes her feel like they don't know her well.
Just my thoughts.
