This feels backwards to me. I understand pdf.tmac to be a low-level macro
package that other packages can invoke. It shouldn't have to know what
packages are going to use it.
Moreover, PRINTSTYLE is a lousy mnemonic for a  flag that alters a
bookkeeping mechanism. It is also stylistically out of step with other
macro names in the package.

Aside from this quibble about a name, the proposal looks sound. I'm
surprised that the time cost is so steep. Is that perhaps because the
density of bookmarks in the test case is unusually high?
