Look, I'm usually among the group who pushes the "there's a mod for that" messaging. And for many mods, that's perfectly valid (as is the case with Izzayo's Gun Pack, which I love but don't think it needs to be in vanilla). But when it comes to QoL features that exist in nearly every other crafting/survival game, I'm becoming more and more of a proponent that it should be included in vanilla, if for nothing else than to give console players a better experience (and I'm a PC player).
For those that don't see themselves using craft from containers, cool. Don't use it. Maybe TFP will even make it toggleable. But at the end of the day, it's better to have it and not use use than to not have it but really want to use it (and can't for console players).
