Its on purpose and he already knows how to do it BIP 110 compliant so there won't be a problem.
Sure, "I" can do it in a BIP110 compliant way. But many users do not know how to do that. If they are using this sample script, or potentially a customized variant that suits their needs, just get their money frozen, for no good reason. Maybe change the BIP to actually target the problem instead of demanding that other innocent people change their wallets and make them worse.
