No official word yet, no. And FWIW, those interested should watch not only to see if perhaps there is a reply here in this thread that Joer has opened, but see also a post I did a couple of weeks ago, as soon as I saw the news.
Bintray, the home of Adobe ColdFusion Docker images, is going away May 1
I and others (in comments) are indeed pressing Adobe to get us an answer before the clock strikes in less than 2 weeks. Sadly, so far no response there from Adobe. I shared also a comment there that I'd reached out to them privately. They ackowledge the issue but offered no detail on any plans.
I encouraged them to offer a comment on the post, so again I recommend folks here watch there, unless perhaps this note here gets attention of someone who didn't see my post (or my email to their support folks). It can happen.
