FWIW, REFRPROT accomplishes two things: use of key 0 storage for reentrant modules whether from an authorized concatenation or not (aside from the cases for which key 0 storage is not used when it is RENT even from an authorized concatenation, such as within TSO TEST when the requestor is not authorized) page-protection of the whole pages within those modules
The former is probably more of frequent interest RAS-wise than the latter, but when the latter comes into play (key 0 module being overlaid) the ramifications can be far more serious.
