One article mentioned one valuable extension for their work (as a future work). I would like to say this in a sentence. However, I do not know what is the correct word to use.
This extension was considered as a future work by A.
This extension was mentioned as a future work by A.
Please note that I am not asking for proofreading, I just wonder which word can best describe the meaning of my sentence. For me, I think both are correct. However, the first sentence says that the authors consider this extension as a future work (they plan to do it as a future work). However, the second one says that this extension was mentioned as future work. But I am not sure if my understanding is correct or not.
