How did the Wine package manage to shave off half its size?

Not complaining, just wondering - I was upgrading my system and noticed that the net upgrade size is -748 MB, with just a few important-looking packages set to be upgraded. So I checked and it's wine - going from 1338 MB (9.9-1) to just 587 MB (9.9-2).

I checked the commits to the package repo, and as far as I can tell, this is the only change between 9.9-1 and 9.9-2 - it removes a bunch of hardening flags and that's it. I know these often come at the price of increasing the final build size, but more than double?

For context, the Arch-wide flags are defined here, if I understand it correctly
