Hi Philipp,
Thanks for getting back & sorting this, sorry I'm rubbish at replying, since I last posted Google has completely changed their font service lol.
I think it would still be good to mention at the very least that these could still be loaded in with font loader on a JS tab (which as you say has been removed).
I would be grateful if the JS tab came back with the code snippet with the web font loader. With Google giving ranking benefits to pages that load faster, why take a faster option away from people?
I think that was the only place that it was referenced.
