Research direction
Start by reading the linked containers issue 890 comment and the experiments at the referenced GitLab project to understand the proposed Data.Set.fromDistinctAscListN API and its timing data. Done would require a settled design and evidence that the construction strategy provides the intended benefit; this issue does not name implementation files or tests.
Written by the indexing model from the issue text.
Description
just making a note that such a function (with N = length of second argument) could be useful, since an implementation can use N to determine the shape of the tree in advance, so there's no need to re-balance during construction.

I made some experiments here https://gitlab.imn.htwk-leipzig.de/waldmann/fdaln and the timing data looks very strange...
