Hi!
So, is there an equivalent for WDQ "AROUND[]" now? :-)
Not yet :) I.e., we could simulate it by accessing longitude/latitude manually, but in order to use BG 2.0's geospatial index, we need to add code to specifically encode our coordinate literals in a way compatible with this index. So there's still work to do, see https://phabricator.wikimedia.org/T123565 There are some interesting challenges due to the fact that our coordinates include globes which is not a very common thing, but we're working on supporting it.
