I think you need to read the explainations that follow each statements from the google document. For example they don't say that they really don't use exceptions, they just cannot use them in their "old" base code (that was relying on old compilers) but allow usage in new softwares.
Just picking titles without reading the whole document (that I feel globally makes sense because seems defined by practicallity) is not a good idea.
By the way, I don't think saying that not using exception (for example) is bad practice, expecially on some embeded softwares. For example in video games on game console hardware it's just not viable as explained in the EASTL document there :

Even Stroustrup (in his last book if my memory is right) says that in some limited environnements you just have to use a subset of C++. It's not bad, it's flexibility.
I personally think that good practice and expeptionally breaking rule code living together is sane. So I don't clearly understand the idea behind the original mail of this thread.
