Generic import-from-URL feature

Posting this feature / plugin idea in hopes that it already exists somewhere.

The feature would allow a user to import the complete contents of a web page to a new topic using a URL. The real value of the feature would be in stripping out all HTML tags, converting formatting into markdown, importing image assets, and converting onebox-able content into simple links.

I suspect that a lot of that magic code has already been implemented for migrations from other forums. So this feature/plugin could be feasible to implement leveraging existing migration packages.

An entire webpage is a bit of work to import. Every site builds them differently. Many sites these days might not even build HTML for users, but instead have the browser import a javascript app and some page specific data then construct the page in browser.
