I am not a fan of case insensitivity either. But it must be easy to write a case insensitive grep. I wager that a nim grep would already exist.
I do agree that this is a red flag decision.

If you use choosenim to install Nim several executables get built/downloaded along with the compiler:
$ pwd && ls
/Users/me/.nimble/bin
choosenim nim nim-gdb nimble nimgrep nimpretty nimsuggest testament
