Other wallets, such as Mycelium, do not allow the user to simply copy and paste the seed. This is very useful to assure users follow directions on the next screen, because previously it was easily possible to just copy the seed and paste it on the next screen. The user's wallet would work well for a while like this, but without having the seed written down it's more of a ticking time bomb than a wallet. I recommend pulling this patch as I have read many cases where users do not write the seed down, and I believe that the main cause is lack of friction forcing them to do so. This patch was inspired by reading this Reddit conversation: https://www.reddit.com/r/Bitcoin/comments/3p4bq1/electrum_v25/cw380kg But I'm not a participant in that convo.
