Option to patch out hardcoded distance limits?

[muzikbike]

e.g. optionally removing the 32 million limit from inf 0313-b1.7.3 and the 30m limit for later versions. If this ever supports snapshots then it'd definitely be interesting to see how 14w30a/b behave at a billion blocks out.

Not sure if this is out of scope since it would require jar modding.
