Yes, I agree with you there. I don't want to force users to this configuration. 
Users that have a reason could still start a dirmngr with --homedir ~/.gnupg.

But maybe it really would be better to have dirmngr read the trusted-certs 
from the sysconfig dir and also from the homedir. 

If --homedir is not explicitly set: Read trusted-certs / config from sysconfig 
dir. Afterwards read trusted-certs / config from homedir and prefer the values 
from the homedir. This would be more similar to freedesktops config_dirs / 
config_home handling. 

I shied away from this as this would be more intrusive and not "GnuPG style" 
(well ok my proposal is neither). But imho this would be nice to have not only 
for dirmngr. As it and would give distributors / admins more options.

Not really.
 a) I'm not sure if werner plans to support the system-wide mode forever. And 
I would not like to stray away from debian packaging so far as to still keep 
dirmngr started centrally as a service.

 b) The default should be the system wide config (if it exists) as this is for 
the users that don't know what a dirmngr is. Those who know / care should be 
able to overrule it.
