I can reproduce this.

(I’m sorry for accidentally misleading you earlier.  Turns out I used
JACK a little longer ago than I initially realized.)

I think it should be pretty easy to fix this:

1) we should generate a single file that is used for generic session
settings.

2) all login programs (including gdm) should include that file in their
PAM settings.

3) the pam-limits-service should extend that single file instead of
attempting to update a bunch of PAM files for a selected list of
programs.
