Something that seems to be being partially considered in these models is browser shares that are growing or shrinking.
For instance it would make more sense to me to "support" IE10 than IE7 even if IE7 has a far greater market share this month. If significant work is needed for IE7, it might have dropped below an age or market share threshold before that work is complete.
By the same logic, it seems fair that mobile browsers make the list on a lower raw market share given that that market is likely to continue to grow for some time.
Putting those rules (particularly for IE) into unambiguous, fair, numeric cutoffs may be hard. Predicting future IE market share depends a great deal on the vagaries of auto update policies and corporate IT departments. For instance Windows XP users are stuck on IE8 forever and there are probably quite a lot of them in corporate America.

I worry less about it being harsh and more that it needs to be lined up with which documents the mobile teams current support matrix [1].
Removing Opera support as a general rule is not an option for us as it contributes a significant amount of readership traffic (6.69%) [2] .
