Yes, but it also makes it difficult to reverse or replace the transaction. If I was a merchant I'd rather accepting a low-fee unconfirmed non-RBF transaction than a high-fee with RBF enabled, because the latter makes double-spend easygoing.
I don't recommend people accepting unconfirmed transactions, because you are creating potential problems for yourself and your customer. If it remains unconfirmed for an extended period of time, you won't be able to spend it and neither will the customer be able to spend their change. The latter is more than fine, because you should be accepting confirmed transactions. The volatility of the fees in recent times hasn't been very kind and there is still a good enough possibility for the customer to be able to push it directly to a mining pool, RBF or not. Which is what my point on this "false sense of security" about.
If you absolutely have to accept unconfirmed near instant TXes, do so via lightning network. Though 10 minutes for a confirmation isn't always undesirable.
