Why would you be interested in dropping the *.jl from the URL? I like that the extension makes Julia packages unique on the web. It is very unlikely that a name ending with *.jl is not related to Julia.
@juliohm I think his point was to drop the .jl and then add it back, so that both URL’s point the same package with and without the .jl extension. This way you don’t have to type .jl into the URL but it still redirects you there. So he’s not advocating not having the extension, but that github will redirect the link
when you rename a repo on github, the previous URL still redirects you to the new one
