type=golf) with golf:course:name=*.The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.
A route of multiple golf related elements as members. Often that is a course consisting of golf=hole in sequence. This can be especially useful to distinguishing multiple courses at the same facility/club.
How to map
Courses are mapped in relations 
of type type=route and
Other Key:golf elements can also be added to relate it to a specific course, for example golf=tee´s and paths to take in between holes.
Roles
Elements will be added with an empty role in order of the holes, the order of the holes can also be verified by the consumer of the data of the ref=* on the golf=hole way 
Examples:
Björketorpsbanan, Emmaboda Golfklubb - One course.Nya Banan, Kalmar Golfklubb & Gamla Banan, Kalmar Golfklubb- Two courses on one golf course facility,
Why
If one tags multiple golf:course=*, golf:course:name=* and golf:par=* etc on one leisure=golf_course it is imposible for data consumers to assign what golf=hole with the ref=* goes to what course. Even if a facility only have one course, it is hard for a data consumer and a computational expensive spatial query "what course does this hole lie inside of?" is needed instead of having the data directly tied to a golf=hole.
Using route=golf also have the benefit in that you do not need to duplicate data on alla golf=hole - making updates eaiser and you could also include other features as members golf=out_of_bounds.
Alternative tagging
One could also put all the course-specific tags on golf=hole, but then you lose the ability to describe the course itself with additional tags. With route=golf you have a relation object to put tags on to describe the course itself.
Courses which consists of different "loops" for each day
