'man 2 open' reports the following error code as a possibility:
EROFS pathname refers to a file on a read-only filesystem and write
access was requested.

Are you suggesting that it's not an app's fault/problem if it tries to
open a writable file on a R/O filesystem? Because it's essentially the
same problem....
