Deleting state of transactional grain

I'm interested in ability to delete persisted state of grains that work in transactional mode. Have found something like that: https://github.com/dotnet/orleans/pull/6830 but it looks like it's not used in official code.

Is there any reason why this functionality isn't allowed?

It would be very useful to allow actually deleting old data from the database.

Start by reviewing pull request 6830 and the official transactional grain state implementation to understand why deletion is not exposed. Trace how persisted state is handled for transactional grains and how database cleanup would fit there. Done should include an agreed behavior for deleting old persisted state, with appropriate implementation and verification.
