We only append to it in this scope, everywhere else we set it directly
There was a problem hiding this comment.
this is used in 3 blackes (sure you don't append and instead directly assign in the other scopes), but it is the same name. I would simply define it once, then append for each (or leave the assign for the others is ok i guess); it just is much easier to grok the fact that we are defining the same variable.

Follows #35535
This isn't yet identical to apply_blockwise, because both this and apply_blockwise have some odd behaviors that need to get standardized before they get combined into a BlockManager method, but this is a move in that direction.
