I don’t feel like the game got harder but more like the OP states, it feels more tedious in some ways. Also more convenient in some ways too though.
Most of the stuff that’s done to the game is pretty awesome and i’m ultimately thankful for the effort and nonstop goodness that happens. I don’t always agree with every change but that’s just life.
I too think that realism can be taken a bit too far - selectively - at times. For ex, I don’t think the gun clip thing adds anything except tedium. Melee is very abstracted. Stopping to reload is inconvenience enough most of the time. You already have a ton of different types of guns and ammo (and ammo types). The clips just add an extra degree of micro that seems overdone for just this one element vs most other things. I don’t see this as an increase in difficulty, as I don’t equate tedium with difficulty.
I didn’t like the exotic melee weapons being made more rare either (more replicas and crap versions instead) because that takes choice away. Probably done in some desire to make the game harder but I don’t see it that way, it just pushes you more towards the ultra plentiful guns. So you have less choice. Find shotgun, done (because why bother with guns that use clips either). I also used to mix bows with melee - silent killing, but with the early push towards guns now, I usually don’t bother with archery anymore.
I used to make it be like a quest to try to find an exotic melee weapon - visit museums, pawn shops, mansions. Now I’m better off just getting books and building my own sword rather than waste time with those locations. By the time that happens I have ridiculous amounts of ammo and a variety of sweet guns. I feel like one of my favorite parts of the game was gutted, and keep hoping someone will make a mod to undo the change. 
I didn’t like the changes to the repair stuff at first but overall, I think it’s good, because it can reduce a lot of repetitive action. I don’t mind more mats being necessary (even if gathering thread is even more of a minigame now - disassembling for thread takes forever - my survivors are more concerned with gathering thread than food/drink)
