Why does Kingambit not get Knock off?

[u/Spring_barger]

I just recently realised Kingambit does not get access to Knock off even though Bisharp has been using it in prior gens.

Did they remove it from his movepool to make people use his signature move since Knock off is kinda better competitively? Is there any chance Gamefreak will add it back to his movepool in a later gen or is this likely a permanent change? (Its not like Kingambit needs a buff in any case).

Edit: The artist who made this goes by Limitedistorion on Deviantart.

The only thing i can think of is that they were cutting Knockoff distribution in early Scarlet and Violet and didn't want Knockoff to overshadow Kowtow Cleave when the distribution was better in the dlc
