It seems we either need a plan that lets rust updates happen without
breakage, or perhaps to have versinoed rust packages so that adding the
new doesn't break the old, and we can flip them to newer per
os/version/cpu as it's known to work.  But I am unclear on the details
and if this actually makes sense.    It is merely clear that the current
situation leads to frequent inability to build :-)
