The bug
In creative mode filling a cauldron from a water or lava bucket gives the player an empty bucket, provided they don't already have one in their inventory. This didn't happen in 1.16.5 so it's introduced in 1.17's first snapshot.

That is not true, in 1.16.4, you don’t get an empty bucket in creative mode when putting water into a cauldron.
Can confirm that this didn't happen in 1.16.4. Reopened.
Might still be intentional though – after filling a cauldron you might want to empty it again, and you need an empty bucket for that.
But you don't want your creative inventory full of buckets do you?
If you want to empty it, just get a bucket yourself!
It seems to still happen in 1.21.4 and with water bottles as well! This makes me believe the issue is with the interaction itself, and makes this the same issue as MC-269237
That is an intentional feature, added in 1.16, please read the changelog for more information.
