True, but maybe I'd still go for it.  inst/include/ is after all the place
via which a any package foo can provide its headers to another package bar
which simply adds 'LinkingTo: foo'.

Currently, the 'cost' of attributes is one extra RcppExports.R, one
RcppExports.cpp and we'd add a new (small, few lines with comments) header
file in a new directory.  Seems fair to me -- but entirely your call.

Restraint in not cluttering user systems is also a good thing. We'd be back
to the need for more/better documentation though.
