After mulling over the last few days conversation, here is what ran through my head:
Instead of investing a bunch of man hours removing things that work fine in the game (repair kits) invest that time in that deep additional crafting, vehicle mods and the like you don't have time for.
You want to kick the game out asap, but are strip mining and replacing systems that work fine and it is just bogging you guys down.. keep your eyes on the prize.
You mention crafting repair kits is too hard, but then turn around and want to make more complex crafting items. If new players aren't sticking around for the easy stuff, they won't stick around for the harder stuff later.
Also when talking about difficult crafting, consider a "kid's game" like minecraft.. and those ungodly complex redstone machines people have been making for years now. If a new player can't make a repair kit in 7 days, theres a problem with how the information is given them, not the process.
As someone else suggested, invest time in the journal and popup tutorial tool tips and the like. People shouldn't have to google something, watch a youtube video, or search in forums to figure it out.
Example: Two friends of ours are regular 7 days players, with more than 1000 hours under their belts. They however do NOT frequent the forums or watch youtube playthrough or tutorial videos.
Day 50 of a17, and they STILL don't understand the new clothing system, what hampers stamina, or the impact of mods vs quality because it really isn't even explained anywhere at all. They don't understand how putting a jacket on can cool them off because it doesn't make any sense at all.
They don't know what all mods are even available, or how to find out what those mods do to help them survive better.
Build that information into the trader quest system, since its already in place. Have the trader give them the instructions like how to make a repair kit, or give you a list of what mods are out there and what they do, but don't bury it in a "new journal entry". Pop the tutorial open, and stick it in their faces so to can either read the info or dismiss it. (Or turn it off in the settings, and have it default to on.)
By the time they realized there was a bunch of stuff in the journal, there were SO many new unread items they just closed the journal because it was overwhelming.
Other games get it right.. they have popup tutorials for every new game mechanic, they don't just bury the info somewhere and hope they can find it. The game mechanics like the repair kit are just fine. Whats missing is teaching players how to use them.
Another good example is the perks menu. They constantly ask why they can't unlock something, and they have to told to mouse over something else to see what they need to do. That info should be server up to them in a popup, like "You can't unlock this until you have x points in this ability" They should have to hunt for it, or ask where the information is.
If seasoned players can't figure some of these things out without asking or an internet searches , new players don't stand a chance...and it doesn't matter how complex or easy a recipe is.. without a robust tutorial system in place, they just won't get the information they need.
