Understandable. I suppose the best way to proceed is to continue the
review, but wait on the libjs removal for final approval.

Good point; I'll contact both maintainers.

Worse come to worse, we can stay at the last version that support
js-1.70, and probably ask the js maintainer to update Rawhide to
1.80-pre, now that F-12 branching has occured?
Thanks, Toshio and Jon, for the inputs.
