You can use template specialization to choose between two variants, but that
only solves half the problem (choosing attributes based on template
metaprogramming). The verbosity is still huge. For variable attributes it may
not be as big a deal, but for class/struct attributes changing them means
redefining the entire class/struct including all of its methods. Being able to
pass true/false to change the packed'ness of a struct would be a lot nicer than
copy and pasting a class definition, changing the name, adjusting the
specialization of each method, and then trying to remember to keep two versions
of every method in sync (or dealing with the cognitive overhead of having both
versions dispatch to another layer so that they can share their code).
