I don't think that's uncommon in applications I see. I've been puzzled
throughout why using things like Boost isn't counted and why this only
seems to be about security, from what people have been saying.
A header-only, or header-mainly, library seems quite likely to affect
security-sensitive programs. On the other hand, the sort of (likely
modified or version-specific) libraries for building the scientific
programs I'm interested in seem to be problematical on the same level as
things affecting potentially security-sensitive system programs.
I am all in favour of unbundling as much from such packages as
reasonably practical, from an engineering and system management point of
view, and have done it. I'm just puzzled by some of the rationale in
