I know.

I would argue it's a "false positive": the header generate.hpp is a
maintenance header used for generating new numeric constants, and the
dependency to multiprecision is optional (inside #ifdef's). It is
however documented, so I'm loathed to just move it. There are quite a
few of Math's dependencies that are introduced via similar headers that
exist for maintenance/testing/optional use, and are not included by any
of the "include everything" entry point headers.
