On these pitches that heavily favour quicker bowling, then Dawson may well get the nod as the sole spinner, but I'm sure Briggs will get ample opportunities throughout this county season for his four-day game to develop. With Dawson being picked mainly as an opening batsman, it does allow Hants to select a specialist spinner (Briggs) while also being able to pick three specialist quicks and also have Sean Ervine in the line-up.Liam Dawson has 7 catches at present from second slip for Hampshire in their current match - he's also keeping Briggs out of the team at present with his SLA's as Dawson seems to be doing a good job and hampshire are going with 4 other seamers.
Briggs isn't a serious test contender for England as he doesn't spin the ball (much) but I'd guess it's a bit worrying for Briggs that he can't get in the Hampshire team and Dawson seems a decent bowler and obviously offers a load more with the bat/ in the field - so Briggs may find he doesn't get all the chances he wants in four day cricket this season unless the weather improves.
Briggs probably will hope to become more effective in the longer format and as you say, he's not a big spinner of the ball, so the more four-day cricket he plays the better picture we will get of his role Hants will want him to play in the side.
