This looks reasonable to me.

How would that happen? I don't have to use file-name-all-completions to 
implement file completion operation. Until recently, company-files used 
directory-files at least for some inputs, to implement file completion.

Would every third-party author who decided to implement their own file 
completion mechanism have to find out about some new, Tramp-related 
variable, and bind it to t in their code?

That doesn't sound great.
