It's so much data that any user of the app would have to have an iCloud paid plan, and it would also swamp any 3G usage plan on an iPad. Both of those would put a chill on sales.
Also, is iCloud secure enough for sensitive military charts? Maybe it is, but even so, explaining that to buyer is going to be a problem.
If Apple insists on this course of action, the eventual solution is probably vector maps. But a good vector mapping API doesn't exist for developers, doesn't work for many maps that only exist as rasters, and will take much R&D to make into a reasonable reality. In the meantime, I would hope that Apple chooses to unbreak the hundreds of popular mapping apps they broke last week.
If Apple insists on getting rid of the old behavior of the Caches folder, they need to deprecate it over the course of a year or so. None of us even figured out this would happen until after iOS5 went live, despite extensive testing from many devs. How this went live is beyond me.
