You didn't "waste" it.

The OP is 100% correct that the weapon used does not affect one weapon the riven is for. But that doesn't mean the riven can't be for the weapon you used, and in some cases it's really not that unlikely that it will match.

For example, once you eliminate variants there are only 12 shotguns in the entire game. Therefore, every time you unveil a shotgun riven you have a 1 in 12 chance of having it match.
