initial report about missing url= for git-lfs remote

+### Please describe the problem.
+
+I was trying to follow https://git-annex.branchable.com/special_remotes/git-lfs/ (only without any encryption), to store at least some data on github via LFS (e.g., for https://github.com/dandi-datasets/nwb_test_data). 
+
+Even though I do provide URL to the `annex initremote` call, it is not stored within `remote.log`:

+so I had to enableremote it while providing URL I become able to `get` the file:

+
+
+Shouldn't that URL be recorded in remote.log? (similarly to `type=git` remotes)
