Shouldn't it be in one of the AppData directories?
I asked that same question on twitter. Here was a response
(https://twitter.com/bmwiernik/status/1419033079495147522):
* But it's not for files that should be user-accessible, like a
library (cf. Zotero has preferences in AppData , but library files in
%USERPROFILE%/Zotero)
* So, for example, in R's case it could make sense for the core
packages to be installed in %APPDATA%/R/R-4.1.0/library" rather than
"C:/Program Files/R/R-4.1.0/library" (either is fairly common), but
user packages should be somewhere more accessible.
Here is a quote from
https://docs.microsoft.com/en-us/windows/apps/design/app-settings/store-and-retrieve-app-data:
"App data is mutable data that is created and managed by a specific
app. It includes runtime state, app settings, user preferences,
reference content (such as the dictionary definitions in a dictionary
app), and other settings"
I don't think libraries fall into the categories of state or settings.
I saw that link, and like you and Gabe, found it somewhat ambiguous.
I don't know bmwiernik, but from the sound of it, he doesn't speak for
Microsoft.
So I would say that I still believe Microsoft doesn't give clear
guidance for this. Yes, %USERPROFILE%/R has some non-Microsoft
precedents, but that's irrelevant. This is an issue to take up with MS,
not with R. Let them describe *clearly* what they want, and R will
(eventually) do it (but probably not before they've changed their clear
guidance).

P.S. I am a former member of R Core who did Windows support. I now
detest that OS. I suspect nobody who is still on R Core doesn't detest it.
