    Chronological history of this changeset:

    1. Bundle 4 (#21270) got merged
    2. Posthumous reviews were posted
    3. These changes were prepended in bundle 5
    4. More reviews were added in bundle 5
    5. Someone suggested that we split the prepended changes up to another PR
    6. This is that PR

    In the future, I will just do posthumous review changes in another PR instead. I apologize for the confusion.

    Addresses posthumous reviews on bundle 4:

    Addresses reviews on bundle 5:

    Code review ACK 693414d27181cf967f787a2ca72344e52c58c7f0. I reviewed this previously as part of #21391. I am a fan of the increasingly complicated bundle numbering, and kind of hope there in the next round there is some way we can get bundles 5.333333 and 5.666667!

    ACK 693414d27181cf967f787a2ca72344e52c58c7f0 (jamesob/ackr/21525.1.dongcarl.bundle_4_5_n_followup_f)

    Built locally and read through the code. Everything here is pretty non-controversial/rote. The first four commits just revert the chainstate parameterization of BlockAssembler methods in favor of making the chainstate a member and (presumably) saving on args.
