But that was rejected.Just my looking at the names of the classes we currently have:- Rate- RateLimit- RateLimiterI find it hard to know what these are doing and the difference between them. Note that none of them are used as a rate limiter (ie implements `LimiterInterface`)I would like to be clear that a `RateLimiterFactory` is used to create an object implementing `LimiterInterface`.Commits-------8be261b [RateLimiter] Rename RateLimiter to RateLimiterFactory

…rInterface to a new namespace (Nyholm)This PR was squashed before being merged into the 5.2-dev branch.Discussion----------[RateLimiter] Moved classes implementing LimiterInterface to a new namespace| Q             | A| ------------- | ---| Branch?       | 5.x| Bug fix?      | no| New feature?  | no| Deprecations? | no?| Tickets       || License       | MIT| Doc PR        |Before we release the RateLimit component.I think it would be a good idea to put the 7 classes that belongs to a specific strategy in their own "Policy" namespace. It is very likely that it will be more strategies in the future and the `Symfony\Component\RateLimiter` namespace is crowed as it is.I decided not to put the `CompoundLimiter` in this namespace as it is not a strategy.Commits-------1e6cea5 [RateLimiter] Moved classes implementing LimiterInterface to a new namespace
