I think there is value in both cases. I've seen many developers that have struggled with regex even with all those hundreds of tools to learn and to build/test regex. This could be useful to them to start with, and they can learn regex according to their time/needs. I see solutions like this as a choice, and the fact that people are using these shows that there is value in having that choice, even if is not obvious to us at first glance.
