DiscriminatorMap integer key

[Hricer]

Why can't I use integer type key in DiscriminatorMap?

#[ORM\Entity]
#[ORM\InheritanceType('SINGLE_TABLE')]
#[ORM\DiscriminatorColumn(name: 'discriminator', type: 'integer')]
#[ORM\DiscriminatorMap([
    1 => RequireReaction::class,
    2 => ResolveReaction::class])
]
abstract class AbstractReaction
{
}

Parameter #1 $value of attribute class Doctrine\ORM\Mapping\DiscriminatorMap constructor expects array<string, class-string>, array<int, string> given.

That restriction was added in #9274
If it works, consider sending a PR to relax this constraint. cc @derrabus

Indeed, that annotation is too restrictive.
