Input shaping on expansion boards

[TechNi]

If the documentation about Input Shaping is up-to-date, it is currently only possible to apply IS to axis motors driven directly from the Duet 3 6HC.

This basically limits IS to any printer with up to 6 axis motors which is probably good enough for many people but not for me.

Are there any plans to enable IS on axes connected to CAN-connected (3HC) expansion boards or is this a hardware limitation of CAN FD?

@TechNi yes this is planned for RRF 3.5.
