Afaik that's a hard limit defined by the constant NGROUPS_MAX, which is
128 for my OS.
Does this mean I have to stick with the 3.0 series, even though the OS
didn't change this value in 10 years?

We added that panic call because there has been a lot of confusion due
to groups being ignored. You should reconfigure your Unix to allow
sufficient groups for sys_setgroups.
