summary: how to cope with one or a few broken tracks on an otherwise-good CD? E.g., can one tell `abcde` to not even try to rip a given track? or to resume after a broken track? If not, should this be a feature request, or is such functionality out-of-scope?

I have previously used `abcde` (called with `abcde -c ~/.config/abcde/abcde-MP3.conf`) to successfully rip several tens of audio CDs to MP3, without undue difficulty, and have documented this @ https://wiki.debian.org/Ripping#ripping_audio_CDs_to_MP3s_with_abcde . (And now that my new players nominally support Ogg, I should try that soon.) However I am now trying to rip some rather-less-good-condition CDs and am having a problem with 2. I'll use first case (a commercially-released (2004) copy of "Give" by The Bad Plus) as an example. In that case, ripping succeeds (e.g., the resultant files sound correct) until track#=10, which hangs with errors:
$ abcde -c ~/.config/abcde/abcde-MP3.conf

In this case, the script seems to hang until forced to abend; the hang is definitely reproducible (on same hardware) despite my efforts to clean the disc. So I wanted to tell `abcde`, "just skip the @#$%^&! track 10! It's broken! Quit trying!" But the following efforts were unsuccessful:
1. Just restarting `abcde`: always fails like

after hanging as previous (though apparently not in exactly the same spot).
2. Attempting to drive ripping program via envvar=CDPARANOIAOPTS. The CD in this usecase has 11 tracks, track#s=1..9 rip correctly, and track#=10 reproducibly fails, so I wanted to tell the ripper=cdparanoia to rip only track=11. After much debugging and reading, I created

The second case is very similar to the first, except for
* a different CD and track#
* `abcde` abends itself, rather than requiring me to C-c.
However, instead of abending the failing track and continuing to the next (what I want), `abcde` abends the entire job, returning to the commandline.
So my current questions are:
1. How can I correctly drive the ripper for usecase={one track fails, rest are good}?
2. Is there currently A Better Way to tell `abcde` to punt on a failing track, but continue to attempt to rip the rest on the CD?
3. If (there is) not (currently A Better Way to tell `abcde` ...), should this be a feature request, or is this functionality out-of-scope for `abcde`?
