I've loaded CRW 2.15.101 (devworkspace enabled) into https://codeready-openshift-operators.apps.cluster-5z4kr.5z4kr.sandbox218.opentlc.com/dashboard/#/create-workspace?tab=quick-add and I see that the tiles are no longer sorted by filename...

00_java11-maven-microprofile-bootable
00_java11-maven-microprofile-xp3
00_java8-maven-eap
02_java8-maven-fuse
03_camelk
03_java11-maven-gradle
03_java11-maven-lombok
03_java11-maven-quarkus
03_java11-maven-vertx
03_java11-maven-vertx-http-booster
03_java8-maven-spring-boot-http-booster
04_nodejs-configmap
04_nodejs-mongo
04_nodejs-simple
04_python
05_cpp
05_dotnet
05_go
05_php-cake
05_php-di
06_idea_rhel

But instead are sorted by the name of the devfile tile, eg., C, Go, Java Gradle, Java Lombok, Java Maven...

So if we want to reorder things so that tech preview items are sorted lower than RH products, we either need a sort option in the dashboard, or some other workaround in the devfile registry content itself.
