I think that people who are stressed about the changes about the crafting system will likely almost never interact with it to begin with on a normal timeframe, unless they specifically start way later with the custom sandbox, and so, not impeding on the gameplay loop we are used to (at the beginning at least).
If we go by in term of hours playing in Singleplayer with a 1h/day setting and with speedup when sleeping, it would be a 168h (an entire week IRL of non-stop playing) on average to survive 1 year from day 1. 1680h (2 months and a week) for 10 years.
In a server who doesn't stop when no one is playing on it (still 1h/day and still starting day 1), it would be 336h for a year (2 weeks) and 3360h (5 months) for 10 years.
If we consider in the future that day 1 to a year would be "early-game", 2 to 10 "mid-game" and 10+ years "late-game" (in terms of the usefulness of the crafting system and the creation of a functioning post-apo settlement), custom sandbox will be a requirement if you want to experience it and not be bored of getting there first.
Of course, i tell that with the current systems, and maybe (surely even) that the NPC's will change how we will survive (since the loot will not be only for us and/or a limited amount of players anymore)
failed the math at first cuz brain fart
