Not really. This CFW alone doesn't mean anything. It's just a few lines of code with a fancy menu built on top of an existing arm9 loader (Brahma).
What people may start building on is Brahma, a project which had gone unnoticed by me and probably a lot of other people until now. However, porting the existing code to MSET and the browser is hard (it's based on ctrulib, which does not simply work there). Maybe it's easier to start from scratch for those entry points.
The key part in all of this is the (now finally public) knowledge on how to patch signature checks, which was released in the pastebin.
