Thanks, Hans, for your advice.

I could edit the font features, indeed, but I run a GNU/Linux OS, and Fontforge cannot edit nor 
generate variable fonts. There seems to be a solution (https://www.youtube.com/watch?
v=xoQuWARCUWI[1] ), but so far beyond my technical capabilities that I cannot consider it.

Yes, it is, but not from the beginning. A great Garamond, the original font was designed by Georg 
Duffner. A few years ago, Google decided to make it a more complete font family : Octavio Pardo has 
done an excellent job with the bolder versions of EB Garamond and its conversion to a variable 
font. However, for whatever reasons, he did quite a rush job with the OpenType features ! Many 
essential features are lacking (despite the needed glyphs still being there), and most present 
features are poorly implemented, with a lot of typographic nonsense (concerning long s and long Q 
or the mentioned italic ligatures, for instance).

I will contact Google Fonts shortly to report on the dozens of problems I have encountered that 
make the unfixed new version of EB Garamond unusable for anything but the most basic uses.
Fortunately, my significantly more demanding needs for a client were met with the invaluable help 
from LuaTeX, but that won't be enough for my own projects, much more complex (facsimile of 
ancient editions), until Google improves this font.
