For emails sent as text to -announce, sure. But. Since we support markdown formatting in news postings that go out to -announce, it seems a bit unhelpful to generate broken links for all those posts.
I agree with the principe, but the question is how reliable we can make it. (One oculd also argue we *should* post those as text/markdown, but I fear that will break even more MUAs).
If I can come up with a filter that converts a broken link from urlize for the known case of markdown links, would that be an accepted solution?
If it can be made reliable, I think that would be acceptable. It needs to be validated that it works in the full chain that we use on the site (we also include the silly obfuscation of email addresses in the filter chain), but as long as that's done I think we can and should do it.
