Although the problem might not effect a majority of the TextMate users (how many people use tablets for everything on their computer?), it is still a very fundamental part of the feature set. That's why I believe it deserves a little attention (read: "slider" :)
Sorry to be blunt, but this idea strikes me as absurd ;)
a) you will be able to disable re-selection in b17 (see my other letter on the subject) b) if Mail doesn't have the problem, clearly it's just a matter of replicating what Mail does, rather than let the user work it out by disabling features.
What's absurd is your "blunt" answer to what was clearly a joke... The *main* point was that even though it might not affect a lot of people, I still hoped it would be considered important enough not to be dropped all the way down at the bottom of the feature request list. That's all... Ho well...
