By touch I think you mean install, upgrade or remove, and of these I guess upgrade is the more common case; do you think it is?
install and upgrade are the common ones, right.
Would the overhead be significant even if the tarball wasn't compressed? I don't understand enough about tar's concatenate and delete performance to risk a guess.
As far as I know you can append files; I'm not sure about "inline" deletion, but even if it would exist, then over time (i. e. upgrades) you would dramatically fragment the file, which reduces or even reverts the initial space saving.
