We're all doing our best to improve Emacs in our free time.  It is 
unreasonable to expect that everything would go fine (with your own 
definition of "fine") in all cases.  It would not be reasonable to expect 
that from a private company, either.

That's a rather strange conclusion.  I already told you thrice that a 
simple way to fix your problem is to set long-line-threshold to a larger 
value (or to nil).
