You're missing that "delegate to completion-file-name-table" means
calling substitute-in-file-name first and then
completion-file-name-table, so it wouldn't do the same. But yes, we
could call completion-file-name-table directly without going through
substitute-in-file-name. The reason why I don't do that is mostly
historical (I first started to do something more clever which didn't
work).

I don't know what you mean here.
