JMeter does not have a published API for creating JMX files.

JMX files are upwards compatible. The intention is to ensure that
there are no breaking changes in the JMX files when new features are
added.
However of course to use any new feature the JMX file will need to be updated.
But code fixes do not affect the JMX format.

No, it is not supported.
Obviously JMeter uses Java to create the JMX files but this is a
multi-stage process: the GUI creates the test plan entries and
populates the properties.
There is code to save the test plan and properties as a JMX file.
