In a medium heatproof bowl, microwave water, 1/2 cup cream, 4 tablespoons butter, and 3 tablespoons honey in 15-second increments, stirring between each, until butter is almost melted, about 45 seconds to 1 minute. Whisk until butter is completely melted, then pour into the large bowl of a stand mixer fitted with the dough hook attachment. Let cool until an instant-read thermometer inserted into mixture registers 110°, sprinkle with yeast, and gently beat to incorporate. Let sit 10 minutes while yeast blooms.
With mixer on low speed, add 1 egg and 1 egg yolk (reserve remaining egg white). Continue to beat until combined, about 1 minute.
In a medium bowl, whisk flour and 2 teaspoons kosher salt. Add flour mixture to stand mixer bowl in 5 to 6 additions, beating on low speed until combined between each, until dough begins to form. Increase speed to medium and continue to beat until dough is smooth, elastic, and sticky, about 4 minutes.
Spray a large bowl with cooking spray. Using a bowl scraper, scrape dough into greased bowl and cover with plastic wrap. Place in a warm location and let proof until risen and doubled in size, about 1 hour.
In a small bowl, combine goat cheese, chives, thyme, and remaining 1 tablespoon plus 1 1/2 teaspoons honey and 1/2 teaspoon kosher salt. Portion into 9 balls (about 1 heaping tablespoon each) and chill until ready to use.
Preheat oven to 400° and grease a 9" square baking pan with cooking spray. Punch down dough. Using scraper, portion dough into 9 balls (about 85 g. each). Pat each ball flat and place a portion of goat cheese mixture in center of ball. Enclose dough around filling and shape into a ball. Arrange in prepared pan. Repeat with remaining dough and filling.
In a small bowl, whisk reserved egg white and remaining 1 tablespoon cream. Brush top of each ball with egg mixture. Top with a pinch of sea salt.
Bake rolls until tops are golden brown and crisp, 25 to 28 minutes.
In a small heatproof bowl, microwave remaining 2 tablespoons butter. Brush tops of rolls with melted butter. Sprinkle with thyme and chives. Let cool slightly and serve warm.
