I feel like this would be pointless as the vast majority of users would
likely download the blockchain from a node that was not enforcing a tip
requirement as it would seem like unnecessary cost as in protocol=E2=80=8Bs=
 such as
BitTorrent there is no such tips in sharing files and the blockchain
distribution is in eccense the same thing. However perhaps I am
underestimating the generosity of node operators but I feel that adding a
cost to the blockchain (assuming that all users add a tip requirement)
would lead to centralisation.
