Of all the Olympic Classes, the Tiger is one of the youngest. Only the RSX and 49er are younger (and the 49er by only by a year). I'm not counting the Elliot 6m, either. It's JAK (just another keelboat - no new technology).
Star - 99 years old (1910) Finn - 60 years old (1949) 470 - 46 years old (1963) Laser - 38 years old (1971) 49er - 13 years old (1996) RSX - 4 years old (2005)
To exclude the Tiger because "it's not the current state of design technology" is a BS argument.
It's already an International Class (a requirement), the mfg has agreed to provide boats (a huge committment) and the Tiger Class gets a significant reason to continue its existence for the next 7 years.
