I already have fixed it for myself, my request was about the default,
so most users don't have to fix it for themselves too.

Why would they have to adjust anything?
Just expand %U to both:
paste(c(
file.path(home, ".local", "lib", "r", x.y),
file.path(home, "R", paste0(R.version$platform, "-library"), x.y)
), collapse = ":")
Then R would install packages to the new location in new installations
by default, but still use packages from the old location if present.
Moreover, this location is going to change the next time the minor
version is bumped anyway.
Cheers.
