The change there was just to mark the methods non-experimental. The
logic was that they'd been around for many releases without change,
and are unlikely to be changed now that they've been in the wild so
long, so already acted as if they're part of the normal stable API.

Are they important? I personally consider the approximate count
methods useful. There was some recent talk of deprecating the
approximate sum, mean methods. But they're no longer experimental and
not going away soon so I suppose they're worth supporting.
