(emphasis added) Why not just make sure BIP 149 will never activate unless BIP 141 has expired unsuccessfully? If BIP 141 should unexpectly activate, then BIP 149 nodes would notice and act as pre-SegWit nodes indefinitely, but remain in consensus with BIP 141 nodes. It might be slightly less convenient for BIP 149 users to upgrade again, but then at least we could start deploying BIP 149 sooner.
