The subject is bit too generic no? Maybe we can talk about the function?
Perhaps:

    connect: make `write_fetch_command_and_capabilities()` more generic

Refactor `write_fetch_command_and_capabilities()`, enabling it to serve
both fetch and additional commands.

In this context, "command" refers to the "operations" supported by
Git's wire protocol https://git-scm.com/docs/protocol-v2, such as a Git
subcommand (e.g., git-fetch(1)) or a server-side operation like
"object-info" as implemented in commit a2ba162
(object-info: support for retrieving object info, 2021-04-20).

Refactor the function signature to accept a command instead of the
hardcoded "fetch".
