Who is the target audience then? Most people who've gotten into riding within the last 5-years have done so before the aggressive marketing of e-bikes. Is it to get in shape, get outdoors, master a skill? And why is also it so important for the sport to be more "mainstream"? For me, I got into this to both get in shape and earn the reward and satisfaction of trying to master something that was difficult (still trying to this day). Mountain biking to me is niche like trail running, free-diving, martial arts, rock-climbing (which a lot of riders I know also do), and fly fishing. These are all individual sports where mastery comes from practicing a specific set of skills and also overcoming a lot of the barriers that are in your own mind. All of these sports also require the mastery of some unique skills, in a unique place, and a very determined mindset. If you remove one of the required skillsets, is it sill the same? Does removing a barrier to something really improve the sport, or even the health of the sport? Here's an extreme example; a fly-fishing rod that casts for you. Are streams jam packed with people or traffic jams at every boat launch better for the sport?
