Both of these seem kind of ugly if you start them from a course 180
degrees off the FAC.

As to a large course change, the procedures designer is supposed to annotate
course-change limitations for procedure entry. See KUDD RNAV 10. But, they
haven't started "enforcing" that requirement of TERPs until the last couple
of years.
