One more idea (and I feel a bit bad for asking, since I dump the hard work on you again - not sure if I'm able to help):

W.r.t. the extenders to the second repeat alternative: spanners have the to-barline property that alleviates the need for manual length tweaks in such situations. Do you think it's possible with reasonable effort (in particular, reusing the code and/or strategy from spanners) to achieve the same effect for extenders? Such that, e.g., in your last example

\repeat volta 2 { b'4 b ~}
\alternative { { b b } { b \repeatTie c } } c4 c

\lyricsto "melody" { Here's a verse. "" "" }
\lyricsto "melody" { Here's \once \override = ##t one "" \earlyExtender #-6 more to sing }

would mean that the extender after "one" (that usually extends to the first note in the first alternative) would be stopped earlier, exactly at the barline? (Of course, in an ideal world, the "early extender" would have a corresponding from-barline property, but I don't think we have any example of such a functionality that we can rely on.)
