If all the ID consists of, then no it’s not.
As long as the part asking for ID trusts the part verifying the ID, there is no need for anonymity to be broken, since the verifier just has to confirm what the asking part needs to know.
Think of it like someone owns a bar and needs to know if a patron is old enough to drink, and the bar owners brother or best friend says “I know that guy, he is old enough”.
Gigabyte has been selling motherboards with a backdoor vulnerability.
And during the GPU shortage a couple of years back they, together with newegg, sold GPUs only bundled with PSUs, but the PSUs were so bad quality that they literally blew up, and if you tried to RMA the PSU they refused unless you sent back the GPU as well.
No, they don’t default to the entire profile.
They default to what is called “known folders”, which is things like the documents, pictures, desktop and and other folders (in effect, the bunch of folders that default show in the left side navigation in Explorer)
The Appdata folder is not included, and that is where these save files and configs belong, and not saving there, and using the documents folder instead, is old and lazyness by the debs.

Further, there is some manner of saved data transference from Final Fantasy VII Remake to Final Fantasy VII Rebirth, but it isn’t all-encompassing. Instead, “certain portions are carried over.”
Well, that is some bullshit.
This is a remake of a single game, and I at least would expect saves to fully transfer.
Those aren’t part of this campaign, and are just games that GOG has.
This is the list of games that comes free in this campaign:
That said though, do buy games at GOG as well, to help them keep going with their good work.
