No.  It would not be offered as an update to systems running R < 2.1.0.

We do not update binary versions for obselete versions of R.  Just look at 
the dates on the directories: 2.0 was last updated on April 19.  And even 
if we did (the 1.9 directory was AFAIR updated for a bit after 2.0.0 came 
out) the version depending on R >= 2.1.0 would not build and so the last 
good version would be left.
