I like the ability to capture HTML pages together with images into one PDF document.
sometimes these work, but the WARC file and the WARC file players are awful. It reminds me of the times that you go to the wayback machine and give up looking for something because the pages take too long to load and are always missing something.
That's what makes it a problem for Adobe and why it should be supported by the #1 document conversion tool.
To be specific I'm rejecting the WARC "archive-the-conversation" approach and wanting something that makes an HTML DOM tree and then turns that DOM tree into a good-looking PDF -- I don't want interactive features preserved in the PDF
