OpenSCAD - where is the 3MF export?

[tingo]

As many people know, I'm an OpenSCAD user. Recently, I have noticed that it complains when I export in AMF format

DEPRECATED: AMF export is deprecated. Please use 3MF instead.

I have the latest package installed

root@kg-core2:~ # pkg info openscad\*
openscad-2025.05.08_2

but the 3MF is not in the list of export options:
What am I doing wrong?

my quick investigation tells me that it needs lib3mf which we don't have a port for
but the github lib3mf will build as long as you clone the dependencies too
