Similar to other packages like this, we could split into subpackage 
python-units-currency-updater, require it from the main package, and announce it 
will not be automatically installed in the next release, and will have to be 
selected in setup.
In the following release, drop any dependency and announce that.
Or do so in delayed -2 and -3 releases if upstream is not updated, as it is 
sometimes a year or two between updates, often depending on changes in 
standards? See https://ftpmirror.gnu.org/units/ for dates.
I could prep a test release -2 and announcement, and at some future time (how 
long?) if no upstream updates, untest to current stable; similarly thereafter 
with -3?
