I would say the long double support has matured enough.

-=head2 The Long Double Support Is Still Experimental
-
-The ability to configure Perl's numbers to use "long doubles",
-floating point numbers of hopefully better accuracy, is still
-experimental.  The implementations of long doubles are not yet
-widespread and the existing implementations are not quite mature
-or standardised, therefore trying to support them is a rare
-and moving target.  The gain of more precision may also be offset
-by slowdown in computations (more bits to move around, and the
-operations are more likely to be executed by less optimised
-libraries).
