Embed manifest

Hi!, this is my first message here, so i hope iam doing it correctly...

Does exist any concept, idea, draft, whatever to make the manifest file
embed into the HTML document file ?

Actually we can embed CSS by using <style> and JS by using <script>, its a
<manifest> tag planned ?
I know that manifest is Case Sensitive and got its own MIME, but also JS
is, and uses camel case too, and MIME.
