 Bitcoin Core Merged BIP-324 and AssumeUTXO Proposals

BIP-324 will allow Bitcoin nodes to communicate with each other over encrypted connections, while AssumeUXTO option is set to allow instant UTXO set bootstrapping for Bitcoin nodes.

 Will AssumeUTXO allow a user to bootstrap a full archival node? 
ie the node will still download all of the blockchain data, but skip the validation, in favour of accepting a specified UTXO set? 
 IIR, as currently implemented, you still download and validate it. Assumeutxo just lets you get a node up and running instantly, while core does the actual validation on background.

The plan though is to allow a "don't bother" option that doesn't download at all. I haven't seen any talk on this direction you mentioned though. What would be the use case for that? 
 Oh boy, can't way for 26.0! My public nodes will cut through from 0.21.1 to 26.0 as soon as released
