start drafting a proposal along this line and share it to get some
feedback. Google docs could be a choice of sharing your draft.

You can find proposals from previous years useful.

Also you could have a look at PostGIS 3D functions
https://postgis.net/docs/manual-3.1/PostGIS_Special_Functions_Index.html#PostGIS_3D_Functions

Best,
Vissarion
ps. note that boost.geometry has its own list so you could alternatively
post there
