I rather meant logical breakage that technical one: no functions are removed,
yes, but if existing applications use cmdline::rdline, they won't have a
legitimate way of getting it anymore. The comment you're quoting was before
the workaround, but the WA exists only to keep ABI and we'd prefer the users
to remove direct accesses of the structure fields by 21.11. To do that, we
give them cmdline_get_rdline() and make it public, not internal.
