Assign file with no extension to a language on VS Code as default

Question

In VS Code I usually open files that have no extension just filename . I know I can change the language syntax with Change Language Mode --> Language that I want but I don't want to do this manually every time I open such a file. Can I make a default to this language every time I open a file with no extension?

I know I can do this:

"files.associations": {
    "*.myphp": "php"
}

But what if there is no extension? Also I want to be able to do this without affecting the other file types (that have extension).

VS Code's globbing doesn't currently seem to have a way to detect files with no extension. Every time someone opens an issue, they point it back to this issue here. They detail their globbing support here.

That said, I do have a hacky solution to this. Put this in your "WORKSPACE SETTINGS" (not your general settings unless you really want this to be global).

{
    "files.associations": {
        "[!.]": "php",
        "[!.][!.]": "php",
        "[!.][!.][!.]": "php",
        "[!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php",
        "[!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.][!.]": "php"
    },
}

This works by adding a rule for every file name length and ensuring that the file cannot have a period in it (up to 20 characters in my example). This is a horrible hacky solution, but if you hold your nose and set it once, you can forget it and things just work. I do this in my dotfiles repo to associate extension-less files with "shellscript".

You an also do this just for a specific directory by using the double star glob: "**/just_this_dir_name/[!.]": "php".
