I may have been looking at a stale load of the page (opened it up awhile ago and only just got around to responding). As for what it says atm, I still think it goes too far. the warning in 7.4 I can support, but I'm not a fan of breaking existing code on a feature that's this old. Ratchet up the warning in 8.0 if you'd like, but error is further than I'm willing to go on this one. > 20 years of code in the wild has not "accepted that fact and moved on".

I agree it's a lousy state, but it's not emergent. -Sara
