Hiya Erik
Plans, yes:
https://github.com/gocd/gocd/pull/12077 - but it's not EOL
quite yet :P. Arguably there are riskier pieces of EOL software within GoCD than Rails right now (Spring Security, Spring Framework) and if things get messy I'm more inclined to focus on pieces with better risk/effort ratios.
The main "messiness" blocker with Rails 7+ right now is that GoCD currently relies on jruby-rack which is very lightly maintained and Rack's Rails integration, and seems to be broken in some way with Rails 7. It's not exactly my personal core expertise, so if anyone has some clue with Ruby/Rails/Rack these days, help would be appreciated. What is confusing to me may be simple to you!
Unfortunately, there are not too many "GoCD people" actively working on things left to speak of :-)
