I found some legit use cases for this, and since it was not very hard
to achieve I wrote a small patch that consumes all the input and writes
a temporary file that then it is hijacked into a file:// uri. It is just
a proof of concept, and in case of being added would require also changes
to the man page.

Subject: [PATCH] Render html from stdin
There are some use cases where consuming the html
from stdin can be convenient. The only possible
way to achieve that is to write the full input
stream and then convert it to a file:// uri.
