The most challenging thing for us is running a new enough kernel to get these features. While upgrading to a newer kernel isn't particularly hard, small companies don't have a lot of engineering resources to run kernels that aren't maintained by their distro of choice (usually on the LTS release).
The good thing is this is solved simply by waiting long enough. The bad thing is most developers can't just pick this up today without a bunch of extra effort.
If you are looking for something you can use with old kernels you should definitely checkout Brendan's perf-tools repo[1]. It takes advantage of older kernel features and works with things as old as ubuntu 12.04.
