I'm aware that I can create a custom build build of Modernizr to detect the features I care about. But is there a way to use Modernizr installed with Bower to detect a specific feature or set of features (such as SVG support) without including the entire library?
Basically when I do
bower install modernizr
I will get the entire library which is more than I need.
That's not the responsibility of Bower.
You can use grunt-modernizr to detect which tests you need and build a custom Modernizr version.
