[2.6.2] New slot syntax doesn't allow nested templates

[LexSwed]

Regarding the new named slots synta.
I have a component which dispatches async request and then uses received value in render. With named slots it was okay to have this kind of structure, so that I don't need to check every time whether the data is there. Is there a workaround for new slots?

Before:

<my-component>
    <template v-if="some !== null"> // this allows to have many nested components that use async data which is null initially
        <template slot="header"> // and here I use slot from my-component
            <span>{{ some.nested.values }}</span>
        </template>
        <template>
            <span> {{ some.nested.anotherValue }} </span>
        </template>
    </template>
</my-component>

Now:

<my-component>
    <template #header  v-if="some !== null"> // check is in computed but still not good
        <span>{{ some.nested.values }}</span>
    </template>
    <template  v-if="some !== null">
        <span> {{ some.nested.anotherValue }} </span>
    </template>
</my-component>
