I must say I'm glad Deltarune feels a lot more realistic. You just couldn't take Undertale seriously with how much it hammered in "being a perfect angel to people who have gleefully murdered children and will continue to do so". This little one-off line at the end is really the only time pacifism is called into question.

Meanwhile the "pacifist" character in Deltarune is slowly becoming more bold and recognizing that sometimes you have to fight and is honestly more serious about this than the "mean girl" like when he killed Fake Gerson and said to abandon Jackenstein or they'd all fall. This game doesn't feel like it's being preachy.
