Could we perhaps simply have procfs remove O_CREAT from the flags
passed by the user?   It is never going to work to create a file
inside a procfs mount, is it?

ps: But I'm not sure this is a POSIX problem, POSIX has no procfs,
and so anything that uses one is outside the bounds of what POSIX
specifies, and into the great vastness of beyond all knowledge -
ie: for POSIX, anything on a procfs is an unspecified operation.
