To put it plainly had the movie just used powered Novas with little to no explanation on how they were powered or doing what they did, the audience would've simply accepted it as par for the course. Because we're being introduced to so many new and amazing sci fi concepts that one more is easy to accept. Especially given everything else going on. These guys are powered guardians from Xanthar who were at war with the Kree, but now have a tentative alliance. Cool that's enough to move further. But now they've established the ground work and in a future movie should they go against what they've already established they'd have to spent time explaining the how and why of it.
