How is it supposed to work to have different components all writing to
/etc/resolv.conf?


As it is now, NM will *always* update
/var/run/NetworkManager/resolv.conf. 

Then, if you configure NetworkManager.conf with
  [main]
  dns=none
NM
will do nothing further.

Otherwise, if /etc/resolv.conf doesn't exist or is a regular file, NM will 
symlink it to /var/run/NetworkManager/resolv.conf.
If /etc/resolv.conf is already a symlink to another file, NM does again nothing 
(because it assumes some other component manages resolv.conf).
