iPhone Why "only" 1GB for tweaks?

I don't understand why the relatively small limitation on how many tweaks my iPhone 5 can handle before it's reached it's limit. Granted, I've more than topped it off with a large margin to play with and it's got 31.8% free, but it seems puzzling that all 16/32/64 have this same limitation. I suppose by the time you have THAT many tweaks, you should reconsider anyways. But a friend told me he used to JB his device to have 2GB of tweak area to play with with ih8sn0w or some tool like that back in the day. Anyways, can some explain on a technical level? Is this RAM usage or what? referring to 'storage' in 'manage tab' on Cydia.

Always appreciative, 1GB is nothing I personally fear, but I am curious.

Whatever is being displayed in 'Storage' under 'Manage' in Cydia but I think that is OS/system part, but why is it 1GB limit? Is that on Apple's behalf of the JB tweakers? I've clearly used quite a bit at 68% or so, but I also have it completely decked out with like 30+ tweaks going and wouldn't expect but a few more over time.

All tasteful in my opinion, but a lot of them to be sure with no noticeably adverse impact on the system in terms of battery or performance.

I'm even loving Ayecon at the moment, and I haven't Winterboard'ed since iPhone 3G days.
