there is currently only one place where we pass a list of indexes instead of a single index, so just fixed that and were good to go.

this is already asserted in the SingleBlockManager constructor, so is not needed here?

fastpath has no effect anymore, now? It is still being used in places internally?

@jorisvandenbossche i think ive addressed your comments, can you confirm?

Yes, thanks.

One more thing, though. For Block, we actually deprecated fastpath first instead of directly removing (only the passing of the keyword, I mean, not any functionality, #19265). I assume SingleBlockManager will be used less in practice, but it's also not much work to still accept fastpath and raise a warning for it for now.
