I added those to the list. Thanks for the suggestions.
I don’t think I understand this one. My English is not perfect but doesn’t redundant mean “not necessary”? Why would someone need such a thing? 
@Elipsus is probably right that there is a good reason why phones usually don’t have space inside, but I think if you consider exchangeable internal modules when designing a new phone it could work. So I redesigned the wishlist a bit and added it under “wishes for future fairphones”.
I like that and it made me think. How about an “emergency circuit” that made it possible to start the phone with just the calling function even if all else fails (e.g. battery is [nearly] empty, you FP has a solar charger but there is not much light because you’re inside [or trapped under an avalanche], you installed an alternative OS and bricked your phone, …).
Do you guys think that could be possible?
