There is another critical point.

Compilation time - and I'm serious about it. Web development
is very dynamic by its nature if you make too many things in
"fancy-template-meta-programming-compile-time"
you'll loose users.

If you try to do all the stuff by GCC/Clang as Turing machine
you'll end with horrible compilation times and unmaintainable
code

For example one of the reasons I use Boost.Asio very carefully
due its header-only nature with almost impossible compilation
times.
