Two of the three are (though perhaps not in perpetuity, but just until you get the achievement or complete the challenge), but I doubt the number of overland mobs I've killed in Stros M'kai is tracked. Or how many times I've killed every boss in every delve. Or how many times I've killed each WB in every zone. Or every public dungeon boss. Etc. And we've hardly gotten started. Also remember that one of the reasons they gave for AwA was "the database."
World boss kills are tracked. The achievements for them are likely stored as a 0 or 1, true or false. If we are talking about a pity rate, then that means a cap, and a reasonable cap would be 10 before the counter reset. So the database is already there. The question is how much extra storage would it take to track a 0/1 vs 9 kills. Depending on the data type there could be no difference, being 1 byte.
I'm nearing 1000 runs of Graven Deep without my second copy of the lead there. It's dropping, and I see it in loot log all the time but at this point my friends, guildies, and I are all sick of running it and even if I had it drop tomorrow I'd still need another copy or to wait for it to roll in one of the vendors. It was extra frustrating because I farmed it very hard the week the Coral Aerie sister lead was in the IA vendor since I need another copy of it too but it just wouldn't drop meaning both leads are up to chance. That is another frustration of going for lore entries for leads is for multiparters your progress is completely stalled out if a problem lead arises.

It's doable, for sure - but they'd have to track a lot more. And they'd be tracking it for every account, which would be a waste because lots of people aren't trying for leads or already have them. So continuing to track the number of times they've killed X, harvested, opened a treasure chest (this would now have to be tracked for every zone), used a treasure map (this would now have to be tracked for every zone), opened a safebox (this would now have to be tracked for every zone), etc. would be pointless a lot of the time. Is it worth potentially adding more bloat to every account? I doubt it, when there are other solutions (increase the drop rates, quit with the double RNG, add more vendors that sell more leads for more currencies).
