I agree on the content of this PR, but not on the targeted branch (4.6). Versions 4.6.0 and 4.6.1 have already been released. Dot releases should only contain fixes and not new deprecations! Also, the change of the type of a property can lead to code that are incompatible between 4.6.1 and future 4.6.x.
I would suggest that this change happens in 4.7 instead.

Hey @patrickallaert

Yes we understand this is not compliant with semver in some regards. Unfortunately we do not plan to release 4.7 as we've been working on the next major already. We need to introduce new deprecations in the current 4.6 release as we want to improve the codebase considerably in 5.0, despite inconveniences it creates for developers. This particular change is also a puzzle to a bigger project where we plan to introduce proper getters on our Value Objects to avoid relying on magic methods - we learned on multiple occasions it has serious performance implications. What's more - the type hint was always present in the doc block and if you haven't been sanitizing the value it could blow up in other places too.

Hope you can understand our decision.
