Timsieved implements referrals, which are a part of the base spec of
MANAGESIEVE. If websieve does not implement them, then it is not a proper
implementation of the protocol.

MANAGESIEVE specifies a method of referrals, specifically because a proxy
server buys you nothing other than increased latency due to additional
round trips to complete any given command.
If POP3 had a concept of referrals in their base spec, there
would be no need to proxy there either.
IMAP gains something from a proxy because you can switch mailboxes, though
referrals are still better in many cases for pipelining clients.

Timsieved supports referrals. Your clients also need to support
Sieveshell is one such client.

Sure. Anyone who has it working with sieveshell does.
