Everyone has their own workflow preferences and some will prefer using a lot of custom abstractions in their work environment. Others may apply a very minimal set of customizations (if they bother at all).

I believe it's better to allow people to choose how they configure their editor rather than making that decision for them.

But it would be better if the default configuration was good enough for most people.

Instead, Vim has a very spartan default configuration. There are good historical reasons for this. But it is a sad history, because it means, most long-time users end up with fairly heavy customisation. And those customisations will routinely be different from everyone else's set up, not just when they want to enact some personal preference.
