Does including a Konami-code triggered Easter Egg negatively impact keyboard accessibility?

On an open-source project I’m involved in, one of our devs added a mini-game for April Fools Day, which could be opened and played by pressing the Konami Code sequence on your keyboard (up, up, down, down, left, right, left, right, B, A, enter).

In a GitHub issue, we received a complaint about the game, which included this line:

… but I hope the Codidact team would have the decency to acknowledge that such “easter eggs” can be disastrous to users with mobility impairments who use the keyboard to control the mouse, and promise to not allow such “easter eggs” in the future.

A couple years ago I spent some time using the keyboard and not my mouse, and personally never had a problem with accidentally triggering something with the Konami Code, because it’s not a sequence that – in my experience – is likely to be typed accidentally. It’s hard to get such a specific sequence if you’re not trying.

However, since I’m not an expert on this topic, I figured it’d be worth it to confirm one way or the other: Is having a Konami Code Easter Egg an accessibility problem, from a keyboard-user standpoint?
