Is there something like a guide that highlights the differences and 
makes a transition a bit easier?

I found this[1], but it only shows differences in CLI options.

Maybe it's a matter of convenience, or they haven't heard that slic3r is 
practically dead upstream.

What worries me is that the CVE in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1034848 also affects 
stable, oldstable and oldoldstable. So, a fix is quite urgently needed. 
Unfortunately, the reporter didn't include the affected versions, or we 
might have ended up with slic3r gone from bookworm as well. I'm going to 
add the versions now.

However, this won't fix the issue. I don't feel confident enough to fix 
it, because I don't know the codebase. Someone with more familiarity 
should look at it urgently.
