You wouldn’t get an RFE for not submitting them, because they are not a required document to be provided with the application. I honestly don’t think it makes a difference other than increasing the amount of what will eventually be outdated stuff. You’ll be updating other stuff in the interview anyway, things like further trips abroad, maybe job changes etc, it’s not like they ever expect a 100% perfectly up to date application before you walk in the door. By the way even if you do upload in advance, you should always have originals with you at the interview anyway. It’s not reducing what you physically bring with.
