Questions about Vue SFC spec

Hi! 👋 I'm a core team member of Vite.
I have some questions about Vue SFC spec.

1. Should <template src="Foo.vue"> be supported? (https://github.com/vitejs/vite/issues/5096)

This seems to be supported by Vue CLI. But this isn't explained in the spec.

2. Should <template lang="html">/<script lang="js">/<style lang="css"> work? (https://github.com/vitejs/vite/issues/10033)

This seems to be supported by Vue CLI. But this isn't explained in the spec.
I guess this should be supported but I wanted to confirm.

1. Doesn't make sense to me. I'd expect a src attribute in a <template> to point to a file with a template extension - like html or pug.
2. I'd expect these all to work. The spec says "... lang can be applied to any block ...". In the case of lang="html", I'd expect it to do the default behavior (process as html).

Thank you for your response! Sorry for the late response.
I closed the first one and created a related issue (#7388) for the second one. 👍
