I can understand a minimum character count on a new post, but on an edit?

If you need to add a letter to a word to correct spelling, you have to add more somewhere else to make up for the minimum character count. Can't the software distinguish between an edit and a new post?

I understand and agree with the decision to go to a minimum character count on a new post. If the minimum character count setting can't be changed for edits only, then so be it, I guess.
