Well, if you want an answer to that: (I'd mark this as a spoiler, but we seem to be past that point already)
They appear sparsely throughout the game in places you will encounter long before end-game, starting with one you need to sneak past in the introduction area, so it kind of sets them up as a point of interest challenge from the beginning. They're not just for the end, they're an important element across the whole game.
At some point a traveller told me I could hit them in the eye, and that's when I realized I could stun them this way.
I tried a few times to destroy one but ended up grinding all my weapons away in the process, and failed.
Eventually on the way to the Akkala tech lab, there was a partially disabled one blocking my way to the lab. (I could sneak past, but I needed to light the torches, and it was making this difficult.) This one, because it had no legs and lower HP I actually managed to destroy. That was kind of a turning point for realizing that I could destroy them.
Finally at the lab, with all those glowing blue weapons on sale, I started to wonder about my own collection of guardian weapons I'd picked up in the shrines. That's when I decided to try these on the guardians and realized I could take them on with these. This again was a realization and point of discovery that I really enjoyed.
I didn't get the master sword until MUCH later, and I thought the continual encounters with guardians, with slowly increasing varieties of success was a lot of fun.
