Here is an example of what I was referring to: [FMServer_Sample](https://github.com/dansmith65/SimpleFM_FMServer_Sample/commit/37483f2622dab559143cab19abc6e74b39a561cf) [SimpleFM](https://github.com/dansmith65/SimpleFM/commit/a1bfbd7bad95c733ffbed2c50ed91b220134110f)

My reason is that I can't imagine a scenario where an *entity* would not want to serialize and unserialize recid/modid. I do think you may not want to at run time, like when creating a record, or forcing an update, regardless of modid, but those scenarios have already been covered by your recent changes to the serializeField method.
