I think the problem lies with the terms WRPG. It just doesnt make sense. JRPG on the other hand makes sense, thats one distinct style for games.
WRPGs terms should be replaced with the two ones that people use, Action RPG and RPG. The RPG is the standard one, you will find this in games like Divinity Original Sin and Baldur's Gate. And Action RPG should be something like Witcher.
But again a new problem appears, where do you put Skyrim and New Vegas? It's a bit complicated with all these subgenres.
Either every game of those is RPG and thats it, or we can add more subgenres, like ARPG, CRPG, JRPG.
I honestly dont have a perfect solution for this mess. Some people found the solution to be is RPG being only games where you create character, have actual role playing, something that stems from Tabletop games, but then we have Kingdome Come, a clear RPG and doesnt do that. But thats probably the closest thing to a consensus, however that will make JRPG and ARPG lose their RPG tag.
RPG could be:
1- Stat based system, your level matters, your gear level determines how much damage you deal, you level up and enemies have a level.
2- Skill tree and perks, a system that the player can create builds with and make different builds by choosing different skills.
3- Choice and Consequence in the dialogue/story (doesnt matter how deep as long as you have it, just have different endings and some significant choice to offer player agency)
4- Customization around your character.
Those 4 core aspects, if they are present in the game, it can be called RPG. All of them, not just 1.
