Julien was specifically referring to the section about preparing, taking 
care of deprecated stuff etc. The baseline GTK version for LibreOffice 
7.1 and master is 3.20. If all the items in the preparation guide can be 
done in GTK 3.20, then it's fine to submit patches for them. You just 
have to be careful not to use stuff introduced after 3.20.
