Why hasn't MemoTrie been updated from 0.6.4?

As reported in conal/MemoTrie#10 and commercialhaskell/stack#2719, MemoTrie-0.6.4 has broken haddocks, which makes it hard to generate haddocks for packages that depend on it.

Since MemoTrie-0.6.5 which includes a fix for the haddocks has been out since 2016-09-11 I'm wondering why lts-7 and nightly haven't been updated? Is it because of the of the additional dependency on newtype-generics?

Relatedly I'm wondering if working haddocks should be enforced more strictly on stackage as broken haddocks pose quite the inconvenience for all downstream packages.

Ok, newtype-generics doesn't support base-4.9… :(

Closing as I don't see anything that stackage could do about this.

Yes the upper bound was introduced in #1863, since MemoTrie added that dependency.

We do enforce haddocks and will put an upper bound in place if haddocks fail unless there are special circumstances (see "expected-haddock-failures" in build-constraints.yaml).

I'm not sure why MemoTrie was added with failing haddocks though, a comment explaining why is missing.
