No, that won't work.

In your builds, how many percent of the packages that did have tzdata 
installed during the build did not have a direct build dependency?

Looking at the dependency trees, I'd assume the vast majority of 
packages where tzdata was installed during the build do not have
a direct build dependency.

This could easily become the nightmare situation where one changed 
dependency somewhere makes 100 packages FTBFS that do need tzdata
during the build, but previously got it installed through other
build dependencies.

Thanks, I do appreciate that.
