I think so. You could also make that same argument about the new authentication feature, ActionStorage/Jobs/whatever.
Yes, of course, _there's a gem for that_ but after having used Django, it's really very nice to have those features included and not have to spend any time thinking/arguing about which Gem to choose and remembering/endeavoring to keep that Gem patched, etc.
there's also administration-zero which is basically scaffolding for admin pages and would be similar to what they'd give you built in if they were to. they consider it outside the scope of rails' responsibility as scaffolding is so easy to make.
administration zero doesn't do much other than install a few gems, and include a scaffold that you can use to generate admin pages akin to django but you do get pagination and search and filters added on top. no magic though just rails scaffolds. https://github.com/lazaronixon/administration-zero
