Will there be an update presets method?

Question

I guess the point curve on linear in the beta is the same as the point curve on medium in previous versions.  So presumably this explains why there is a preset for Tone Curve - Strong Contrast anymore, ie that Tone Curve - Medium Contrast is the new Strong Contrast.
But what's going to happen to old presets (depending on how they were created) that use sliders which aren't there any more and/or settings which no longer apply as the base line number is now zero?  How is it antipated this will be dealt with?

Thanks Victoria, here's a simple example for the rest of the community
2010 Preset
s = {
    id = "0BE0B0C9-2E25-4792-A68E-8FCF9E9911E7",
    internalName = "aaaaaaaaaaaaaaaa",
    title = "aaaaaaaaaaaaaaaa",
    type = "Develop",
    value = {
        settings = {
            AutoBrightness = false,
            AutoContrast = false,
            AutoExposure = false,
            AutoShadows = false,
            Brightness = 50,
            Clarity = 0,
            Contrast = 25,
            Exposure = 1.16,
            FillLight = 0,
            HighlightRecovery = 0,
            ProcessVersion = "5.7",
            Shadows = 5,
        uuid = "F95D1ECB-1AF9-423D-8DEA-9162D353CC16",
    version = 0,
2012 Preset
s = {
    id = "E01B6552-9231-47D4-AB60-6BC16BDC29B3",
    internalName = "bbbbbbbbbbbbbbbbbbbbbbb",
    title = "bbbbbbbbbbbbbbbbbbbbbbb",
    type = "Develop",
    value = {
        settings = {
            Blacks2012 = 10,
            Contrast2012 = 10,
            EnableLensCorrections = true,
            Exposure2012 = 0,
            Highlights2012 = 0,
            LensProfileEnable = 0,
            LensProfileSetup = "LensDefaults",
            ProcessVersion = "6.6",
            Shadows2012 = 0,
            Whites2012 = 0,
        uuid = "178152A4-F966-4FE0-8581-38E366E34A1E",
    version = 0,
Both merged to one
s = {

    internalName = "Preset-4-both",
    title = "Preset-4-both",
    type = "Develop",
    value = {
        settings = {
            Blacks2012 = 0,
            Contrast2012 = 0,
            Exposure2012 = 0,
            Highlights2012 = 0,
            AutoBrightness = false,
            AutoContrast = false,
            AutoExposure = false,
            AutoShadows = false,
            Brightness = 50,
