The smart match operator (~~) is always available in 5.10 and above, whether you explicitly use 5.010 or not.

The features which an explicit use 5.010 enables are:

I agree with you that the releases since 5.10 have not been especially compelling feature-wise. Some of the features are nice, but they're not world-changing.

package My::Foo 1.00 {
  ...
}

[download]

... is nicer syntax for starting a package, but it's not so awesome that I'm willing to drop compatibility with pre-5.12 Perl just to use it.

Auto-dereferencing hashrefs and arrayrefs for each, push, shift, etc saves me... what? Three characters max?

Which is not to say that p5p are wasting their time. There are no doubt other, less visible changes which are big wins, but I haven't seen anything to get massively excited about since 5.10.

I think perhaps 5.18 will be the next time we see something interesting added to the language, because part of the 5.16 development seems to have been about getting a better structure in place for building use 5.XXX-dependant features.
