Apparently that was caused by issues in my updated bitmapset
serializer; where I used bms_next_member(..., x=0) as first iteration
thus skipping the first bit. This didn't show up earlier because that
bit is not exercised in PG's builtin views, but is exercised when
WRITE_READ_PARSE_PLAN_TREES is defined (as on the FreeBSD CI job).

Trivial fix in the attached v4 of the patchset, with some fixes for
other assertions that'd get some exercise in non-pg_node_tree paths in
the WRITE_READ configuration.
