FYI, after 2 years of break, I got back to working on Gedcom 7. In the last few days, I worked on a library which can form the basis of a new Gedcom 7 import addon. It is written from scratch and does not attempt to parse invalid Gedcom files.
This is not ready for testing, but wanted to announce it early in case somebody has input.
It’s based on an improved version of my parser
