Experimental

When a feature or reduction is marked as experimental in VW it means that there may be changes to the design, interface or functionality of that reduction or features. This is to allow new things to be added and used without the immediate requirements of following semantic versioning compatibility requirements. It can then be iterated on until it gets to a place where it seems stable, at which point it will be marked as no longer experimental.

Something may be added as experimental due to the fact its design is still being iterated on or it has not had enough usage and testing to be satisfied of its stability yet.
