I've opened #36683 for the example-minimal-python-* failures.

I am not entirely sure I understand why are we doing this change. Should all ARROW_PYTHON dependencies be added? what about S3 or GCS?

[jorisvandenbossche]

Also, shouldn't we in theory not rely on this in our own CI, given that it is a deprecated option?

If the minimal python build needs this, then we should just enable ARROW_ACERO directly in that build? (or update it to not require acero)

[kou]

Sorry. This is needless.
I thought that this is the cause of #36680 but it was wrong: #36683

I thought that this is still needed because #34711 removes ARROW_COMPUTE from ARROW_PYTHON instead of replacing ARROW_COMPUTE with ARROW_ACERO.
But it's correct because ARROW_PYTHON depends on ARROW_ACERO implicitly: ARROW_PYTHON -> ARROW_DATASET -> ARROW_ACERO

[kou]

I withdraw this because this is needless.
