Any reason why BART does not have a ForTokenClassification variant?
Are there any theoretical constraints to create a ForTokenClassification variant for BART? In my current project I am using a sequence classification head + a token classification head, so I would like to implement the token classification part manually. However, since it is not implemented in the repository, I wonder if there are any particular reasons why one should not do this. 
No theoretical reasons, go for it!
