I semi-understand the split between link button and interaction button but personally I'd rather have one Button class that then changes its type based on what you set in the style (so something like <S extends ButtonStyle>(style: S): S extends ButtonStyle.Link ? Omit<this, 'setCustomId' | 'whateverElse'>& Pick<ButtonComponent, 'setUrl'> : Omit<this, 'setUrl'> & Pick<ButtonComponent<T>, 'setCustomId', 'whatever'>, of course simplifying the types like I did for the slashcommandbuilder (where it has a subcommandsonly and options only type)
