Has anyone go online with legit unbanned console recently since the big change in CDN system last week, and bought and installed an actual eShop game.
Then modded their Switch, and dump and extracted their nand backup, to see if 'nintendo' infact with legit game bought thru eShop, stores these so called extra worthless metadata (xml's/jpg's) files on your Switch nand.
Maybe the problem is two-fold, not only are the previous dumps 'wrong', but maybe the current nsp installers, are not 'installing and looking' for all the files that the real switch does with legit eshop.
Remember tinfoil and other apps are all based on devmenu and early cdn tools, and devmenu is from early system firmware, it does not mean that even tho everything works fine now without this 'extra metadata', that it is not at least tracked and logged or stored by nintendo themselves at some point during the whole actual legit eShop buy,fetch,install process on the switch.
And you got to remember also, even if the above is 'useless' right now, does not mean in future like with v6.0 firmware when 'paid online' launches in 3 to 4 weeks, that these 'files' are now 'needed' and 'logged' and 'looked for'.
