"submodule foreach" much slower than removed "submodule--helper --list"

In v2.38.0 (31955475d1c283120d5d84247eb3fd55d9f5fdd9) "submodule--helper --list" was remove because

> We're not getting anything useful from the "list | cut -f2"
> invocation that we couldn't get from "foreach 'echo $sm_path'".

But we get speed (this is with about one hundred modules):

$ time git submodule foreach -q 'echo $sm_path' > /dev/null

real 0m0.585s user 0m0.413s sys 0m0.182s

$ time git submodule--helper list > /dev/null

real 0m0.008s user 0m0.004s sys 0m0.004s

Please consider restoring this subcommand or providing something equivalent that is just as fast.

     Thanks,
