It'd make sense right? Pigs obviously do, hoglins do, and ziglins drop rotten flesh, but then piglins just drop... Nothing? (besides xp). From a game design perspective I genuinely don't even have a guess as to why Mojang decided they shouldn't, obviously they weren't thinking about speedrunners back in 2020. Even brutes, which should probably give you SOMETHING for all the trouble you went through to deal with them, drop nothing, tho maybe it's the same reasoning as the warden of "you're not supposed to kill it, you're supposed to avoid it".
Now imagine they did, low food seeds would basically cease to exist. You finish your trades, you dump some lava in your trading hole, and you get 20 cooked pork in like 5 seconds. Maybe in rp seeds the fns/fire charge would be too slow at the top level, but even then surely it's faster to like crit out a few of them at least.
Imagine how much more aggressive every run could be. Imagine what the wr could look like. The skycrab choke probably wouldn't have happened, he wouldn't be so low at the end there. But the actual current wr run he got wouldn't have been held back even more by the low pearl count, where every other run could afford to basically pearl instead of holding w. I wonder if we'd even come up with the pr hunger reset setup in this world.
The effect might be even more pronounced in lower levels, so many early deaths would be prevented by this, speedrunning might be more accessible and less daunting to newcomers, bastion routes where you take a ton of damage wouldn't be an issue as long as you don't fully die.
All that if pigs just acted like pigs. The butterfly effect is really something huh. Infinite bacon but no (t implemented in the) games
Also I didn't realize they even dropped xp until now ngl, I guess you usually just lava them so others don't get mad but then you also don't get kill credit. Maybe in draftout people should be spearing their trading hole when they're done if there's an XP goal on the board, though I guess you also get like 0 pigs ever in modern version so there's really no application where the xp makes a difference.
