[syslinux] Is chain loading EFI apps not supported?

[marteg]

Greetings!

If I understand everything correctly, the last release of syslinux 
supports UEFI, but it can't load another EFI application in this mode, so 
practically only linux kernel can be bootloaded. Unfortunately, I have a 
need to dualboot windows and linux with UEFI, and this holds me back from 
using this amazing piece of software.
Have there since been any progress regarding this issue? Are there any 
plans to implement this in the future? Can I help somehow?

Sincerely,
Martynenko Egor
