Came across this post and also find an interest in this. It would be helpful to make props read only even though we can see property history (that is a great feature btw 
)
To add to this, can it not be possible to make some read only props non-read only? Eg. the create date and some other date fields? Use case would be so if importing old data we can set the old create date - this is also useful for reporting.
Thank you
