Tus-Version: 1.0.0,0.2.2,0.2.1

seems like over design. The list will get very long over time.

Just use a single integer instead and have the header include min and max version supported. E.g.

Tus-Version: 1-4

meaning it supports version 1 thru 4. No reason to be able to say version 1 and 4 but not 2 and 3.

We are discussing this very topic here https://github.com/tus/tus-resumable-upload-protocol/issues/... — it has stalled a bit so I would be very happy to see you or other interested/concerned HN readers weigh in. People sharing concerns on GitHub is the main way the protocol has progressed.
