Right, it's relevant to the extent that it's ... not relevant :-)

OK.  [ Tho I feel it is kind of silly, since as soon as you consider
actual examples, it should become obvious that it has to be the case.  ]

I use it in email messages, because I consider it to be the better term,
from a technical point of view.  But indeed, I don't use it in the docs,
because it's too late to fix it there.

Kind of.  I still don't understand how/why it helps you, but at least you
say it does, which I guess is good enough.
