This is a problem which needs to be addressed and fixed independently.

This issue should be fixed first, not as part of some large-scale patch.
If you have thoughts or ideas about how to address this problem as it
relates to views, I think you would find alot of people willing to
listen and to discuss it. This must be independent of SELinux,
independent of row-level security, and isn't something based on any of
the patches which have been submitted so far. None of them that I've
seen resolve this problem in a way that the community is willing to
accept.
Thanks,
