Make WebView.set_content()'s URL argument optional
What is the problem or limitation you are having?
Currently, the url argument in set_content() is required. But it stands to reason that, if you are directly setting raw HTML content, that content doesn't have a URL associated with it.
What we can currently do is pass an empty string to url:
my_webview.set_content("", content=html_content)
But that's clunky.
Describe the solution you'd like
In the set_content() function, make the url argument optional.
Describe alternatives you've considered
Perhaps #2851 can make this issue obsolete.

Your assertion is incorrect - even if you don't specify a URL, a webview has a URL. That URL might be about:blank - but it's still a URL, and it can impact how page content is interpreted. GTK, iOS and macOS don't have an option to not specify a URL when loading content.
The closest we could do here would be to set it up such that mywebview.content = "<html>..." is an implicit call to mywebview.set_content("", "<html>...") - but the additional complication is that most web APIs don't provide a way to retrieve the page HTML content - so we need to define a setter, but without a getter.
Syntactically, that's not something Python allows - but I guess we could define the getter, but make it raise AttributeError so that it looks like it doesn't exist, and document that it's a write-only property, and advise that the setter is equivalent to set_content("", content).
