Bluetooth Mesh: Extended advertising and Mesh directed forwarding

[Naama-TI]

Hi,

I'm using the Bluetooth Mesh project and would like to start using the Extended advertising feature.
I have a few questions:

1. Since I will use the extended advertise, I would like to use its ability to send large unsegmented messages.
   Is this planned to be supported? If not, is it safe to increase the value that determines the max unsegmented msg size (BT_MESH_SDU_UNSEG_MAX)?
   Currently, the max msg size is 380 bytes and each segment max size is BT_MESH_SDU_UNSEG_MAX (11 bytes).
2. Does the ability to use legacy and extended advertise simultaneously (instead of only one of them in build time) will be supported before Mesh profile spec 2.0 will be released?
3. Does Mesh directed forwarding is planned to be supported? If it is, do you have an estimation when?

Thanks in advance
