It does not prevents me at all or anyone else I suppose too.
I just found that for some users it is confusing and
some users do not recognize those tools as general purpose ones.
Also, there is a kind of psychological effect of yet another third party
dependency that may make some users to avoid those tools :-)
I say what I've experienced when I tried to suggest to use the FP
algorithms in Boost.Geometry (GGL). I saw Boost.Test FP algorithms
seem to be used in Boost.Graph and perhaps others, but it looks
like exceptional cases.
Simply, my understanding is that those algorithms state a well-known
robust implementation of floating-point comparison and as such
it is recommended to be used across Boost libraries so their clients as
well. Thus, a bit of promotion seems beneficial :-)

I think it some sort of math utilities would be a good place.

I'll stay tuned.
