Description
Composer does not appear to load the files section of the autoload definition for plugins. This appears to hold true for the plugin itself and any dependencies, I expect this might be a design decision but I cannot see it documented anywhere. I've stumbled upon this while investigating a problem with the new releases of symfony/yaml package using PHP 8 functions breaking plugins on PHP 7.4 which led me to symfony/symfony#42280. I've put together a test plugin to demonstrate the problem.
My composer.json:
{
"repositories": [{
"type": "git",
"url": "https://github.com/cs278/composer-include-test-plugin"
}],
"require": {
"cs278/composer-include-test-plugin": "@dev"
}
}
Output of composer diagnose:

When I run this command:
php -f composer.phar test-plugin -vvv
I get the following output:

And I expected this to happen:
PHP/7.4.21
str_contains? YES (user-defined)
bootstrap.php included? YES
Yaml::parse? Array
(
[foo] => bar
)
