@posva of course, here's an example of what I do all the time when writing components in plain JS function render() {

props.isOpen && h('div', [])
])

Also Vue 2.6 allows booleans: export interface CreateElement {
(tag?: string | Component<any, any, any, any> | AsyncComponent<any, any, any, any> | (() => Component), children?: VNodeChildren): VNode;
(tag?: string | Component<any, any, any, any> | AsyncComponent<any, any, any, any> | (() => Component), data?: VNodeData, children?: VNodeChildren): VNode;
}
export type VNodeChildren = VNodeChildrenArrayContents | [ScopedSlot] | string | boolean | null | undefined;so removing it would be a breaking change |

Right, booleans make sense for jsx
