I will, given the option, write around using the post-fix operator, as well as use it in trivial examples such as OPs. Preference has everything to do with it, that's entirely what a style guide is based on.
Practicality, readability, and - most importantly - consistency are what style guides are based around. What they "should" be based on, in your proposition, is entirely your opinion.
