also im unsure if the support for oversized transfer is guaranteed for the lifetime of a session? could it be withdrawn in between? if yes which signal invalidates it?

Gret work, mergin.
About your question, it cannot be withdrawn mid-session. It's a one-way latch, by design. support, once learned, holds for the lifetime of the transport instance; only close() → clear() resets it.
