Comment:
This was discussed in #35124 recently and at lead to
[https://forum.djangoproject.com/t/could-bulk-update-aggregate-the-pks-in-
when-clauses/27093/2 this discussion] about the complexity of and cost of
hashing certain values quickly. Unless you can provide benchmarks that
this is actually faster I think time is better invested towards #29771 and
#31202.
