Currently, no. The extended instruction set allows the device to access additional instructions, but at the expense of loosing access bank memory. The main reason for the use of this instruction set is to allow reentracny, which is currently not supported by the compiler. Reentrancy may be introduced in future versions and this may well require utilization of the extended instruction set.
