I am concerned about long term storage with hygroscopic oil in part due to JSmith1983's experience related in
Devil's Spit Theory.
As OP included a link to a published science article about caster oils ability to inhibit acidic corrosion. My use of BIG words was an attempt to stay in the tone of the OP, while including a search term that can be used to easily find related information.
A coating that would inhibit acidic corrosion would be good in some scenarios. But if that coating would encourage rust by absorbing watter that would then be held to the blade. The value of the features would have to be carefully weighed.
In a short daily rotation scenario, the hygroscopic properties of a coating is much less of an issue than in a long term storage scenario. However in the short daily rotation scenario the pivot would likely collect some of the coating. The pivot would then be at greater risk of rust due to the hygroscopic properties of the coating. Potentially causing eventual rust even on razors that have never had watter in the pivot.
