`composer.json`: empty string in `autoloader-suffix`

[WinterSilence]

My composer.json:

{
    <...>
    "config": {
        "autoloader-suffix": ""
    }
}

Output of composer diagnose:

Checking composer.json: OK
Checking platform settings: OK
Checking git settings: OK
Checking http connectivity to packagist: OK
Checking https connectivity to packagist: OK
Checking github.com oauth access: OK
Checking disk free space: OK
...
Checking composer version: OK
Composer version: 2.3.4
PHP version: 7.4.27
...

When I run this command:

composer update -W -o

Actual result: class ComposerAutoloaderInit... {...}(autoload_real.php)

And I expected this to happen: class ComposerAutoloaderInit {...}

IMO having an empty suffix is a bad idea, as the point of the suffix is ensuring different projects get unique class names in case they coexist in the same process. So you can set it to your project's name or something if you like, but don't use empty.

Clarified this in #10725

@Seldaek in your case, bad idea is same suffix for loaders and no matter empty suffix or not. But in cases when uses single autoloader is's better then useless suffix.

I understand it's not what you wanted to hear, but I also don't see a huge problem with having this suffix set to something.. This classname shouldn't even appear anywhere in your code.

This classname shouldn't even appear anywhere in your code.

Nope. Case: project declare N autoloaders, your code in vendor package. Question: how you get Composer autoloader to get registered namespaces?
