IMO this will bring forth more confusion that it'll solve. Technically, 
the ABI is linked to kernel and library versions rather than dates.
Since Linux, unlike commercial products, is not locked into a particular 
vendor and thus doesn't have a single product life cycle forced upon it, 
those vary wildly between distibutions and running installations.
