It's probable that on the platforms that use fontconfig that we just
split the list of font candidates at ; and ask fontconfig for a
replacement based off that first entry if the first one is not
available, so that debugging fontconfig itself likely doesn't matter
too much. In the sense that it's too late when fontconfig is asked its
opinion about a replacement[*]
Yes I had noticed this too but wanted to know how fontconfig did it.
But indeed, perhaps it won't be necessary.

Whatever about the case of a document/user explicitly using ";" to
suggests fallbacks where the first one that really exists might be a
good idea, I feel the other case where LibreOffice is just asking for
"something good" probably should continue to just feed fontconfig the
first entry and accept that result.
...
I've submitted https://gerrit.libreoffice.org/c/core/+/173140 (put you
in cc) to try to use the fallback font list in priority.
