[v5.1][EntityExtend] How to add interfaces, traits to ORO entities

[xgitxhubx]

Hello,

I have an ORO project (v5.0) that has already used entity generator extension in order to add our custom interface implementations and traits.

But I have just seen this commit: https://github.com/oroinc/platform/commit/1f27d354fa418eead8f17b2a27d20c050238aa58

It means in v5.1, we can not add custom interface implementations, and traits to existing ORO's entities?

Do we have another way to do it?

Could you please help?

Thank you!
