I don't see it, and like the other commenters, it seems like the design space is just constrained enough that the projects would have to have some similarities.
Regardless, if you think you're being copied, just copy right back. I suggest imitating the DX.
As someone who tried devenv (and nix-darwin for a while), before eventually returning to homebrew and mise, I really wanted to like it, but the nix complexity kept leaking out.
Mise does maybe 80% of what I did with devenv, but at only 1% of the hassle.
