if possible can it be simplified into
userMetadataMapEntryNode.CreateChildElement("key").SetText(mapItem.first)
and
userMetadataMapEntryNode.CreateChildElement("value").SetText(mapItem.first)
from the codegen?
i.e. can we support chaining for the setters at a node level for all its immediate children?

One way I have dealt with this in the past is from java (using recursive function and a context) to generate the code and then just use the code in the template. This will greatly simplify the velocity template and push the computation on the Java side

Both key and value types can be other than Strings,
please refer to a generated example:
the current approach is to create a parent element following the model, then create key/value elements following the same model.
The macro serializing the each individual element does not care about if we are within Map or List, it just knows the current
item
to be serialized under the currentparent
.Trying to optimize the appearance of generated code will make the codegen even harder.
Move to generating the code to .java is also quite debatable.
It may appear to be easier on a first glance, but on a fresh look, the complexity looks equal. The .vm allows to match the generated output to the template, while the simple streaming of new code into the buffer using any programming language does not.
The current goal is to make SDK compliant with protocol tests.
Refactoring and optimizations of generated models will follow later.
