Ext4 is most certainly still in use and not a toy. Its trusted. It takes a lot for folks to adopt a new file system.
I worked on a research topic in grad school and learned about holes in files, and how data isn’t removed until the last fd is closed. I use that systems knowledge in my job weekly.
A tip. Kernel development can be lonely, share what you are working on and find others.
