TrueNAS Mini XL+: Status? (discontinued/EOL?)

In this thread I was encouraged to migrate from CORE to SCALE. I also noted in that thread that iXsystems continues to sell Mini systems with CORE preinstalled. Given that plugins and CORE are being aggressively deprecated, can you explain why Mini’s are being sold with CORE? How will my TRUENAS-MINI-3.0-XL+ perform under SCALE? Any advice and insight you can provide would be greatly appreciated.
