Maybe the one on CRAN needs fixing...

I don't want to be argumentative, but the perpective of "obvious"
can often be quite different from one of the authors versus one of
the users...

The 32-bit/64-bit issue affects purchasing or upgrading decisions
- whether one wants to spend the money on buying cheaper
32-bit machines, versus more expensive 64-bit machines. That
decision would be based on information available while *not* having
an operational R installation...
