LilyPond breaks lines, and breaks pages after having established how the
lines look.

So this is not something that a "feature request" can do.  The best you
can hope for is telling LilyPond where it can break the page including
key signatures and so on and forbid it to break page anywhere else.

It can even be a range of measures that you are sure will take more than
1 line and less than 2.
