That's not how this worked in the past AFAIR. Simply, the packages in
the x.y.z/Recommended directories were included in
src/contrib/PACKAGES*, metadata, with the correct R version
dependencies, in the correct order, so that `install.packages()`
automatically installed the correct version without having to add
extra repositories or manually search for package files.
E.g. right now we have

Package: Matrix
Version: 1.7-0
Priority: recommended
Depends: R (>= 4.5), methods
Path: 4.5.0/Recommended

for R 4.5.0. IMHO what we would need for R 4.4.0 is adding
something like

Package: Matrix
Version: 1.7-0
Priority: recommended
Depends: R (>= 4.4), methods
Path: 4.4.0/Recommended

*after* that.
