That only affects stuff that goes through PAM (specifically, all PAM
stacks that include pam_limits.so).

It is my intention to change this system wide, i.e. for system
services (which do not go through PAM) too.

Lennart, what is the path forward here? Should we pull in some security experts to give us recommendations on the best default value? Or are those conversations already happening somewhere else? Also, do you need any more information regarding the Wine esync use case, or has Zebediah provided sufficient data?

Thanks.
