Ordinal logistic regression traps

I have seen this post and that post about ordinal regression. It is strange to learn that SPSS and Stata uses a different modeling approach than SAS and Minitab. Also the SAS way explained in the second post is very important to remember when doing ordinal regressions with SAS.

SAS contrasts and lsmeans

SAS Class parameterization

I noticed that some SAS procedures do not provide some parameterizations like using a keyword like param=GLM. Then those procedures(GLM, MIXED, GLIMMIX, PROBIT, and ORTHOREG) only provide GLM parameterization and usage of "ref" keyword in a class statement as described in here.
