• Question; if the requirement is to have a flush weld, should a reinforcement weld be applied and then dressed off flush, or should the groove be welded flush?

RE: Flush groove welds
I have had this discussion with several in the past, and even with cap grinding, there is still a small portion of the HAZ which does not get tempered unless a temper bead type technique is used.
There are lots of things to consider. Especially the material type, service conditions, and the amount of grinding. In general, it's a good practice, but you don't want to be counter-productive either (manually grinding 200' of weld).

However for some common sense do's not prevail and as AWS D1.5 is not a code I'm working with, I'm still left with the controlling code of AWS D1.1
