I think it all depends on the size of the team.

Very small team and too many design docs, not good.

Huge team, multiple timezones, multiple squads, and few design docs, not good either.

And then you balance with all the values in between depending on your team size & culture.

Even within the same company, your approach will/should change as it grows. There's a critical point where move fast and break things approach will eventually end up with too many outages, production bugs, unpolished/confusing product, and last but not least, FTC eye watering fines.
