I entered YC as a solo-founder with Wasmer, so I think it might just be a circumstantial thing (they receive a lot of applications so it's always hard to judge who should enter with the limited time and data they have to make a decision). I would really encourage you to apply again! In any case I'd love to help you on both aspects (YC application and OSS), I believe your idea has really great potential. Please ping me to syrus@wasmer.io and we can schedule some time to chat!
