(1) If a user installs sbcl for the first time, there is no previous copy.
(2) The previous copy (if exists) can be very old, contain bugs etc. The 
build process on users' computers will be not reproducible: if some user 
reports a bug, we don't know which version [s]he used for bootstrapping. 
If we ask him/her, reproducing the bug still becomes more difficult: first 
rebuild the urer's previous version (by the way, using which 
previous-to-previous version?) and only then try to reproduce the user's 
immediate problem.
