New variations of creepers?

You know how zombies and skeletons have variations like the drowned, husk, and stray? Maybe we could do something like that for creepers? Here's an example: The stalker. The stalker spawns in darker areas and burns in sunlight. It follows the player from a distance and stops when the player looks at it, and it could even run for cover. However, if the player drops their guard for too long, the stalker will silently explode.
