[Interface-dev] Idea: Interface versions?

[Jim Fulton]

I'm reviewing a ZODB pull request that adds an attribute to an interface,
IStorageTransactionInformation, to create a new interface,
IStorageTransactionInformationRaw. Sigh.  I hate having to create a new
interface for such a trivial change.  Sometimes, I punt and define
"optional" attributes.

I wonder if it would make sense to version interfaces to allow interface
evolution without having to come up with new names [1].  IDK what form this
should take.  This is just a thought and was wondering what others might
think.
