It your own personal choice to delete your character regardless of what the reason is. When XIV came out I stopped playing XI to play XIV with no plans play XI anymore but I left my character data in place, guess what earlier this year they had a free login period and I decided wth and decided to login and since I didn't delete my characters they were still there for me to play. So deleting your character(s) is your own choice/fault they not there anymore and no reason to change the 1 time restore rule.
