As noted here, by @Calle and @obetz, a danger is presented if Partial Presets are based on an image that contains Local Adjustments (that can cause Local Adjustments to be removed from any other image to which the partial preset is applied).
This reinforces the importance of being aware that a local adjustment has been applied to an image - and reminded me of the request logged here/above.
An easier-to-implement solution (from that proposed above) would be to include a check/tick or some icon on the Local Adjustment button. Something like this:
… for images to which any Local Adjustment has been applied.
