Hello,
(1) the status of Pro CDN functionality:
We don’t have a time set for that, and it’s possible that we will not sunset it after all.
The goal for this plugin is for it eventually, primarily, make use of Kits, which has a separate CDN from the Pro CDN, which had been planned for sunsetting. So I expect that this plugin will always provide a way for WordPress users to load Font Awesome Pro without self-hosting: whether continuing with the Pro CDN, or through the CDN that powers Kits.
(2) Self-hosting and the plugin:
This plugin is designed to facilitate loading Font Awesome from Font Awesome’s CDNs. If you’d like to self-host Font Awesome, you could consider following the pattern shown here for doing a custom installation of Font Awesome. You would replace any CDN URLs in the code samples with URLs to your self-hosted location.
If you choose to self-host, I recommend that you also closely consider whether your mix of theme and plugins involves any Font Awesome conflicts. That’s the other big thing this plugin is designed to address. So if you go with a custom installation approach, you may need to also handle conflict detection and resolution yourself. For that, too, you could follow the pattern in the code samples here.
