That was quite literally my first thought upon seeing the proposal as well. Nice idea, it'll blow up in Reikas face judging by VERY similar previous circumstances re: "nagging the user".Given how well the update checker went over, I doubt this to be viable. As soon as I implement such a feature it is going to me met with as much criticism from pack makers as the update checker was. In fact, probably more, as it will probably be characterized as "punishing the pack maker for deviating from 'muh vision'".
The big problems I see with this are the inevitable actions of the community. If (and here's the weak point) a pack becomes popular with this wuss mode, then the realistic version is severely diminished simply because nobody will want to play it, which will make all popular packs have it on, and then why even have realism as a core principle. The casuals "won" and anyone that doesn't want to play casually has lost. If one more person says "you can change configs yourself" I am going to scream, by the way. There are plenty of safe options for power, ReC is unique in that it tries for realism and consequences for failure. Giving in (and that's what it would be, this kind of wuss mod has been suggested before, even if not implicitly; one of the biggest complaints/cons about Reika's mods is how "hard" they are) would quite likely worsen the experience for anyone playing Reikas mods right now that actually enjoys the current gameplay. Options that become popular become PACK DEFAULTS which is how the VAST majority of users are exposed to mods. This will, if it becomes popular (which the MC community LOVES making things easier and have fewer consequences), force ReC into a significantly changed experience... which the author doesn't want, and I don't think most of the current players that enjoy the design aesthetic would enjoy either (I wouldn't mind either way. But I'm strange).I approached it more informally: I'd have a single main thread for my pack, and it would be in big bold blue letters. The gist would be "Reika allowed this because he's nice to you and the pack wouldn't work otherwise, but if you have a normal-world game running you'll probably appreciate it more with the default settings."
That's what you might be missing here. This option, judged via the lens of past stated community opinion, has real danger of becoming the majority option. Which pollutes the artistic vision of the mod. So while the implementation is trivial, and it fits a use case? The risk is too great for the reward.
