It is bending policy, but I liked python3-community-louvain because the
package name "python3-community" is just an exceptionally vague name. I
think it's clearer if the name of the algorithm is in the package name.
Also while looking through scanpy's louvain function I learned of yet
more implementations of louvain. (Look through this function for
different "flavors")
https://github.com/theislab/scanpy/blob/550b82fdb53f35890e60343b826dd19454600bdb/scanpy/tools/_louvain.py#L23
Apparently what I'd previously called "igraph", scanpy calls "vtraag"
because the vtraag version builds on the louvain implementation
in python-igraph.
There's also yet another version in nvidia's rapids library.

I wasn't sure how much effort to put into saving the previous Debian
louvain package since it didn't look like it was really usable by
anyone.
Libraries.io makes it look like the python-louvain "import community"
version is a bit more popular and more actively developed. The "vtraag"
version has a comment in it's REAME saying the developer deprecated it
in favor of leidenalg (an improved method).
On the other hand scanpy thinks the vtraag version is the most feature
full implementation of louvain and uses it as their default.
