remoteLink deprecated in Grails 2.4, now what?
Basically, they're removing the tags because they don't add much value, and instead contribute to bad design patterns - they're too low level. It's usually best to play within whatever Javascript frameworks you're using, and make higher level tags that make the AJAX calls for a purpose, rather than having a Grails tag JUST for making an AJAX call.
