It drops symbols so effectively this includes a transition.  Only one
rdep (qflow) with same maintainer.  I cannot tell if it uses the symbols
(codesearch.d.n does not respond to the search and I don't have time to
check manually).

I believe we need an ABI bump for this.  Will check up and get back to you.
