My understanding from reading the documentation is that
get_node_processes is returning static information, simply stating
which processes are defined for each service (in CM terminology, the
set of role types that belong to a service type). It's not attempting
to reflect anything about the actual structure of an instantiated
cluster.

The "get_node_processes" function is needed to display supported
services and node-processes at UI. The list of node processes
should be specified in node group to tell plugin which process
should be started at instances of the node group. In file-based
configuration flow plugin should set node processes per node
groups, so, there is no need to pass any additional info to this
function.

words, if this is used in places other than template creation,
since an advanced(plugin specific) configuration is not passed,
the plugin will only return default data, which may not match the
specified advanced configuration.
