Just curious, I think the original one is fine, and I have seen other repos doing this.

Are there some rules that disallow this?

[meteorlxy]

It's all fine. Just don't want to add complicated @typescript-eslint/naming-convention override 😮‍💨

[meteorlxy]

@Mister-Hope Reverted. It should have been supported in eslint-config-vuepress@5.1.4
