Yes, there are in fact a lot more SUP surfers in the line-up than there used to be. And yes, unfortunately there is still conflict between conventional surfboard surfers and SUP surfers. Werner paddles put together a good little video on SUP surfing etiquette. And while all surfers should practice etiquette, SUP surfers should be aware of the need to practice respect and aloha not just some of the time, but all of the time. Aloha!
