No need to make the "Final" call (note - no 'S'
) Once you've got the clearance that's it. I've done the same in the past to make life easier as Mike suggests.
I think the comment about situational awareness is a bit of a misnomer, as it sounds like there was no other traffic to be situationally aware. As for the vehicles comment again, another misnomer - you can't receive a clearance unless the runway is available. If there's going to be an incursion it doesn't matter whether you call Final or not, ATC should be checking the runway anyway.
Wheely
Why do you need a Final call to give a more up to date wind reading? You give it if you feel it's necessary, no matter what call you have or have not had made. If it hasn't changed since last given it isn't necessary.
