If the majority of the network decides to deploy SegWit, it would be in
your best interest to validate the SegWit transactions, because you might
will be downgraded to near-SPV node validation.
It would be okay to still run a "non-SegWit" node if there's no SegWit
transactions in the chain of transactions for your bitcoins, otherwise you
cannot fully verify the the ownership of your bitcoins.
I'm not sure the practicality of this in the long run, but it makes a case
for having an up-to-date non-SegWit node, although I think it's a bit of a
stretch.
