So I've tried again. I've good and bad news.

Good news: I can no longer reproduce the session startup failure. GNOME
starts just fine, and this is how the two services in question look:

-----------
  $ systemctl status --user dirmngr.service
  ● dirmngr.service - GnuPG network certificate management daemon
     Loaded: loaded (/usr/lib/systemd/user/dirmngr.service; enabled; vendor preset: enabled)

  	      Main PID: 21509 (dirmngr)
  	         CGroup: /user.slice/user-1000.slice/user at 1000.service/dirmngr.service
  		            └─21509 /usr/bin/dirmngr --daemon --homedir /home/zack/.gnupg

Bad news: I checked where the services belong in the service tree (as
you suggested on debian-devel [1]) and they are still not part of the
session scope:

-----------
  └─user.slice
    └─user-1000.slice
      ├─user at 1000.service
      │ ├─gpg-agent.service
      │ │ └─21508 /usr/bin/gpg-agent --daemon --homedir /home/zack/.gnupg
      │ ├─dirmngr.service
      │ │ └─21509 /usr/bin/dirmngr --daemon --homedir /home/zack/.gnupg
      │ └─init.scope
      │   ├─21502 /lib/systemd/systemd --user
      │   └─21503 (sd-pam)         
      └─session-1209.scope
-----------

FWIW I've checked and there are no other dirmngr or gpg-agent services
running in the whole tree.

Is this the expected behavior? In your test where did the two services
ended up being located in the service tree?

Hope this helps,
Cheers
