@mardy Are we discussing language packs as clicks, or a more general solution to "what apps are installed by default" when flashing a phone? Because those seem like two separate things, and we should not use one of them as a reason to do another thing (or to not do some other different thing instead), I think.
I'm not using one as a reason to do the other, but rather I'm explaining how I imagine this evolving into, to convince you that we can get a nice user experience even with selectable language packs.
I also disagree with the idea of anecdotal argumentation of well, it's a waste in the rootfs for me, so why should it be there for others. I think it would be best to not go down this route. There are plenty of things in the rootfs which are meaningless for me too.
And what I'm suggesting is that, if those things could easily be installed as clicks, and if doing so would save a considerable amount of space, then it's something we might want to try out. It's a question on whether it's worth the effort.
I did start with language packs because I thought that it would be an easy pick, since they are data-only. And so far it looks like it's something easily doable.
Maybe having langpacks is something we will need to do in the future. But I think right now, we should not rush into this as a solution to the problems we have, as there are plenty of larger concerns at the moment. And if we rush into it, we will be stuck for a long time, even if we discover some other solutions to whatever problem this is meant to solve, instead.
I'm not requesting that people spend their time on this. If @bhdouglass told me that he has no time to review the changes I'll eventually submit to the Open Store, then I certainly wouldn't force him, but it looks like he likes the idea as well.
And I'll try not to rush: I do want to see a good implementation of this (especially because, as I said, I plan to apply a similar scheme for navigation data, later on).
Could I spend my time in a better way? Probably, but I'm doing this as a hobby in my spare time, so I tend to work on those things that interest me first :-)
