I think the general view is that the old APIs will likely be good to go
for at least another year or so, especially since they were un-deprecated in
0.21. (Which would mean that 0.22 would be the next opportunity to
re-deprecate them, then have them removed in 0.23). IIRC, one of the changes in
0.20.203 is to remove the deprecation flags.
