First of all, quantify the breakage. Does the proposed change break
`make check-devel`? Does it break CRAN and BioConductor? (This one is
hard to measure properly: someone will have to run >20000 R CMD checks
times two, for "before the change" and "after the change".) Given a
persuasive case, breaking changes can still be made, but will require a
deprecation period to let the packages adjust.

If you would like to try your hand at developing a patch and make a
case for it at R-devel or the Bugzilla, the resources at
<https://contributor.r-project.org/> can be helpful.
