You might be interested to know that pg used to have a fake XA
implementation in the driver as well.

I don't think a straight lines of code count can really indicate the
difficulty of implementation. If the backend API matches up with the XA
API then you can easily write even thousands of lines of boilerplate code.
If the APIs don't match then you may have to do some complicated mapping.
All of the real work for XA is on the backend side.
