I'm fully aware the OS doesn't care about the extension. The extension is there solely for my benefit when writing code. At a glance I can tell which language I used to write something. I could use file or look at the first line myself, but a simple "ls" is all that is needed to view everything. A "find . -name \*.ext" is much easier to find everything written in the same language than anything else you can come up with. It is all about my convenience, not the OS's. 'ls' can even be setup to colorize each file by the different extensions.
When a program goes from being "source" to executable, the script is copied, extension removed, and chmod'd. I know these steps are completely unnecessary to the OS, I could easily be modifying a 775 script directly without having to "make" it, but this is for me. When I want to find something I did in a perl (as an example) script, I can easily search just the perl code across many subdirectories.
I am consistent with the extensions I use, so I have a standard.
I don't link to the executable so that the original is still usable while I'm making changes. If I'm inclined to check it, I can still do a quick diff to make sure I didn't have any accidental editor changes.
When I started out 30+ years ago writing programs, I didn't put the extension on because it wasn't needed for the OS then I realized it was valuable to me. It is only in the source code directories, so only I see it when I'm editing.
I wouldn't expect or want to have the extensions on anything in my PATH.

But, or course it produces executables with no .exe extension. For a shell script, it's the #! line which tells the kernel to run it in a shell, and magic numbers for other types (which is all the same thing, and how "file" works).

This is proper use of Unix, not demanding file extensions. Unix is great, but it's expert-friendly, and not as windows claims to be "user" friendly.

While this seems unnecessary, besides making it easier for vim know how to colorize the code, it also allows the use of find/grep for searching.
