Is it necessary for parents to have to submit written permission for a child to go by a nickname?

I was browsing Reddit when I saw a post made by a Florida teacher who said their county is making students get written permission from parents to be called by a nickname. This is crazy to me. I found a news article which gives the gist:

So Madison can’t go by Maddie and Nicholas can’t go by Nick. Is this what conservatives mean when they say they don’t want the government in their business? Now kids can’t go by a preferred nickname? Thoughts?
