I've seen and heard some end of phrase emphases of the dominant that sort of blur the line between tonicized half cadence and modulation to the dominant. Take for example the ending of the A section of Bach's Air from Orchestral Suite no. 3. Most would consider this to be a modulation to A. But to me, that A doesn't feel like it's a conclusive phrase ending and I only really hear A major as tonic at the start of the B section. I would analyze it as a tonicized half cadence, especially at the first ending.

But I have it on my list for my music theory book I'm writing for a totally different reason. the descending 5-6 sequence aka "Pachelbel Progression" that occurs at the beginning of the A section with its I -> vi -> IV descent, the very backbone of the progression.
