Interesting that kinda works, what about teaching git-remote to
understand a "--prefix-tags" option which would create the
"fetch = refs/tags/*:refs/remote-tags/origin" entry. And teach
git-fetch to use that entry if it exists and not require the "--no-tags"?
Of course I'm sure there are "lots" of other things to change, doing
a search for "remotes/" gives the following:
$ find . -type f -name '*.c' | xargs grep '\bremotes/' | sort -uk1,1
./builtin/branch.c: fmt = "refs/remotes/%s";
./builtin/checkout.c: skip_prefix(argv0, "remotes/", &argv0);
./builtin/clone.c: strbuf_addf(&branch_top, "refs/remotes/%s/", option_origin);
./builtin/describe.c: !skip_prefix(path, "refs/remotes/", &path_to_match)) {
./builtin/fast-export.c: "refs/remotes/",
./builtin/fetch.c: else if (starts_with(rm->name, "refs/remotes/")) {
./builtin/merge.c: if (starts_with(found_ref, "refs/remotes/")) {
./builtin/pull.c: * refs/heads/<branch_name> to
refs/remotes/<remote_name>/<branch_name>.
./builtin/remote.c: strbuf_addf(tmp, "refs/heads/%s:refs/remotes/%s/%s",
./builtin/rev-parse.c: handle_ref_opt(arg, "refs/remotes/");
./builtin/show-branch.c: if (!starts_with(refname, "refs/remotes/"))
./contrib/examples/builtin-fetch--tool.c: else if
(!strncmp(remote_name, "refs/remotes/", 13)) {
./help.c: if (skip_prefix(refname, "refs/remotes/", &remote) &&
./log-tree.c: else if (starts_with(refname, "refs/remotes/"))
./ref-filter.c: skip_prefix(refname, "refs/remotes/", &refname) ||
./refs.c: return refs_for_each_ref_in(refs, "refs/remotes/", fn, cb_data);
./remote.c: FILE *f = fopen_or_warn(git_path("remotes/%s", remote->name), "r");
