I'll reroll tomorrow morning in case there are more comments until then (particularly about PARSE_OPT_KEEP_ARGV0). This new code doesn't take advantage of it, and it's very rarely used in Git itself, thus its use here is a potential source of confusion, so it's probably best to drop it.

[PATCH v2] remote: add get-url subcommand
Expanding `insteadOf` is a part of ls-remote --url and there is no way to expand `pushInsteadOf` as well.
