Why the extraneous default git urls? (original) (raw)

Why use git urls like https://git::@github.com/mileszs/ack.vim.git for the repositories?
There're some personal repositories which I push directly from the plugins directory, but I have to change remote urls to standard for the push to work on GitHub, and then, change it back to this non-conventional url so that vim-plug doesn't think there's a problem with the plugin when I run :PlugUpdate.
