In investigating a package which included its own copy of Eigen 3.3.9
and gives C++17 warnings, we found that 3.4.0 (which is already 20
months old and available as a Fedora RPM) had resolved those warnings. R
CMD check currently skips reporting them for users of RcppEigen. Things
like (example from Apple clang, also seen with LLVM clang 15/16)

Eigen 3.4.0 has an alternative using std::invoke_result, used for C++17.
So an update to 3.4.0 would be beneficial now many RcppEigen users are
compiling with C++17.
In response I pointed the 1 1/2 old (and stuck) issue #103 but noted that I may not have the bandwidth or inclination to carry this forward as I an effectively a caretaker maintainer who stepped in many moons ago when the initial maintainer moved on.
