One question remains: why was it changed?
Instead of more or less simply calling the vallue via ly:grob-extent
we now have to calculate it, looking at each Accidental separately.

Just curious.
I must have missed that change.

Well, it happened before 2.17.5 as near as I can tell.

I'll look at this some more, but the problem appears to be that there is no 'elements array for AccidentalPlacement.  You call ly:grob-extent on the AP, which relies on the setting of 'X-extent, which is ly:axis-group-interface::width.  This latter function ultimately uses the contents of the elements array.  accidental-engraver.cc creates AccidentalPlacement grobs, but not an elements array.

I can't figure out where that 1.1 comes from, though.

HTH,
