P: Tone Curve Enabled not copied by Sync, Auto Sync, Presets, Snapshots

[All the problems with the tone curve toggle switch not getting copied by Copy/Paste Settings, Auto Sync, Sync, Snapshots, and SDK's photo:getDevelopSettings() were fixed in 7.4.  Adobe has decided not to fix the problem with presets:

[See this post for a precise recipe for reproducing the bug: https://feedback.photoshop.com/photoshop_family/topics/pv2012_snapshots_not_saving_tonecurveenable_s... 

Also, the SDK method photo:getDevelopSettings() fails to return the parameter "EnableToneCurve", which is surely a symptom of the same underlying bug. See:

--John Ellis]

I created a snapshot, made some adjustments, then selected the snapshot, but it looked different than when I took it.Traced it to the ToneCurveEnable setting which was disabled when I took the snapshot, but enabled after selecting the snapshot further on down the road.Note: ToneCurveEnable setting is not in the develop settings when read by plugins/SDK either - I'm guessing there's a connection.This bug was logged a long time ago (against Lr3), but not fixed.Adobe: Please acknowledge this bug and fix in next release, OK?

    I was told a day ago that I discovered a new bug and that it would be fixed in the next release. Here I find it's an issue at least five years old. Color me late to the party, but color Adobe later 😉    LRuserXY's point 2 above is a decent workaround. Crosspost: https://forums.adobe.com/message/9305841#9305841

    Problem still exists in Lr5.6.

    Related problem: tone-curve enable/disable setting is not accurately readable/writable via plugins either. All the other enable/disable settings work OK.

    And there are some other inconsistencies:

    1. It works the other way round, i.e. selecting a snapshot with tone curve enabled while the tone curve is disabled, enables the tone curve.

    2. Snapshots that are *updated* (rather *created*) work *correctly*

    Oh, and I just found out the development presets exhibit the same behaviour, but worse: They don't change disabled -> enabled and are not "cured" by updating.

    LR 3.6 and LR4.0 64 Bit, Win7.
