The base packages R attaches to the search path on startup, so their exports are usable without a library call.
This is what a plain R session attaches, which the code we read never states: R_DEFAULT_PACKAGES,
--default-packages and options(defaultPackages=) each change the set without leaving a trace in it.
A project that changes it says so through solver.assumeAttachedPackages; see attachedBasePackages
for the version-aware view, as a release cannot attach a package it did not ship.
