Unable to access any private properties (such as Item.LastConditionChange) by StatusEffect

Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

I guess Item.HasBeenInstantiatedOnce is also not working properly, perhaps because the access modifier of these properties is private?

Reproduction steps

Add the following code to guardian pod

<StatusEffect type="OnDamaged" target="This">
  <ParticleEmitter particle="shrapnel" anglemin="0" anglemax="360" distancemin="-60" distancemax="60" particleamount="1" velocitymin="200" velocitymax="300" scalemin="0.7" scalemax="1.2" colormultiplier="198,154,148" />
  <Conditional lastconditionchange="lt 0.0" />
</StatusEffect>
<StatusEffect type="OnDamaged" target="This">
  <ParticleEmitter particle="shrapnel" anglemin="0" anglemax="360" distancemin="-60" distancemax="60" particleamount="5" velocitymin="200" velocitymax="300" scalemin="0.7" scalemax="1.2" colormultiplier="198,154,148" />
  <Conditional lastconditionchange="lt -5.0" />
</StatusEffect>
<StatusEffect type="OnDamaged" target="This">
  <ParticleEmitter particle="shrapnel" anglemin="0" anglemax="360" distancemin="-60" distancemax="60" particleamount="5" velocitymin="200" velocitymax="300" scalemin="0.7" scalemax="1.2" colormultiplier="198,154,148" />
  <Conditional lastconditionchange="lt -10.0" />
</StatusEffect>

Damage a guardian pod, you will not see any particle emitting

This is actually intentional. There is usually a reason for a private property to be private: modifying or using them might for example require some additional logic or require deeper knowledge of the inner workings of the class. That's somewhat the case with LastConditionChange and HasBeenInstantiatedOnce too: the former is used in the vanilla game in conjunction with ConditionLastUpdated, and HasBeenInstantiatedOnce cannot really be used by status effects in any meaningful way because a status effect can't target an item that has not been instantiated.

Does this mean that HasBeenInstantiatedOnce cannot be properly serialized and deserialized as well? After extracting the sub-file from the game save file and decompressing it using a gz tool, I found that HasBeenInstantiatedOnce does not seem to have been written into the XML.
