I see on Commento.io it explicitly mentions being able to import from Disqus comments, but the "Import from a different service" is behind a signup wall.

Rather than signing up for a service that may or may not work for my site, I'm curious, does it allow importing from existing native Drupal and/or WordPress commenting systems?

That's my biggest pain point right now. Exposing public login to my CMS is a security risk (see: plugins/modules with permission escalation bugs) and frankly a pain I don't want to manage anymore. Migrating old comments to a new system is preferable to keeping the legacy comments system (and user accounts) in place while maintaining a second system on top of it for new comments.

Importing from Wordpress isn't officially supported yet, but others have found workarounds. One person imported their Wordpress comments into Disqus and then imported that into Commento. While native support within Commento would be infinitely better, I thought I'd mention this for the time being. I'll consider this comment as a vote for native wordpress import support :)

Related (if the creator is still around): Is there a roadmap/timeline for SSO?

I plan on implementing SSO for the next release (v1.7.0), but I've been a bit busy with school work for the past week or so. Still about ~2 weeks away, by my estimate.

Oh wow, great.

I'm used to roadmaps and software planning cycles in months or years so "weeks" is probably before I could even get somebody to open an email to start thinking about this. :)
