Or perhaps the script is imperfectly guessing which binaries are Python 
2?  e.g. matplotlib is listed even though it's already a Python 3 only 
package.

Very likely: by "tangle" I meant 
https://en.wikipedia.org/wiki/Strongly_connected_component

i.e. not a single cycle, but you still can't remove any subset of them 
(other than all or none) without breaking at least some of the remaining 
ones.

If the question is still open for discussion, I'd also prefer letting 
Suggests be temporarily broken over making extra uploads to remove them. 
  (I haven't checked how much this would break up the 159-tangle.)
