I would also oppose a typedef. You may not see the const after the *
very often, but it would still take more time to look up what a certain
type StrPtrWhatever_t means.

I like the approach of this patch and given that it really brings
benefits, there is no reason not to merge it.
This may be an example of where the C type system comes to its limits,
but as you already said well, the principles of information security
apply well here.

With best regards
