No, just to be clear: *there is absolutely no dependency on the PP lib*.

It is true that there are a couple of headers which have a "maintenance
mode" that includes PP headers - but the result needs a search and
replace afterwards to produce valid C++ code. No user code can ever
include a PP header via type_traits. Ever.

To make this clearer, one thing I considered was archiving the PP
generating code somewhere, and removing it from the headers.
