[JE] Fix or mitigate MC-301649

MC-301649 was recently marked as Working As Intended. The bug report is here: https://bugs.mojang.com/browse/MC/issues/MC-301649

The change, made in 1.21.2, causes many mob search ranges, such as villager iron golem searches, to have large random variations. This causes existing designs for iron farms to be unreliable, and may increase lag for farms that rely on spacing to mitigate entity searches, such as bartering farms.

This could be fixed by creating a separate, fixed attribute for these search ranges to use instead of FOLLOW_RANGE, or by removing the randomness from the attribute. Alternatively, this randomness being reduced somewhat would still be helpful.

I cannot see a drawback to removing the randomness on these particular sensors. In normal gameplay the ~3 block differences between the maximum and minimum follow range will hardly be noticed, but it has large negative impacts for technical applications.

    Hello everyone, OP here. I would like to point out that MC-301649 does not completely break iron farms forever, as some of you seem to believe. It just makes them slightly more annoying to design, but newer designs (from people who know what they're doing) will work fine in 1.21.2+, and are not very different from older farms.

    At they point it feels more likely that minecraft will get replaced by an indie knock off, because things seem to be slowly slipping further and further down hill...

    minecraft sweats when they have to W-W-WORK for iron instead of creating a farm that generates 10 million every nanosecond: 😡😡😡😤😤😤
