From the sounds of things, it would be easier and probably more efficient
to just always convert to dense binarized matrices, unless we have a good
case for requiring sparse handling of labels. In particular,

Sounds good to me. Only I would like some confirmation on whether
deprecating support for sequences of sequences is sensible.
Sequences of sequences and arrays of sets are both iterables of iterables,
right? So,

Sorry for the late answer. It's hard for me to keep track of all the
design-related discussions lately.
No worries. Thanks for the reply!
For me, the advantages of the sequences of sequences format are:
- they are
TL;DR: do we need to support two forms of multilabel targets? sequences of
sequences may have unexpected behaviour.
With Arnaud Joly's recent implementation of multilabel support in a number
of metrics, there has been some extensive discussion of multilabel targets
and their format at
