 ports' distfiles to change, which would necessitate changes to every port
 using the github portgroup, so before considering doing so I would want to
 understand the benefit.

 Perhaps I'm restating things that are already known, but from the
 discussion over on #46241 ...

 While playing w/ the GitHub API, I discovered that the old API is
 redirected to a legacy API, e.g., the prior
   `https://github.com/user/repo/{tarball,zipball}/{branch,tag,sha}`
 is redirected to
 `https://codeload.github.com/user/repo/legacy.{tar.gz,zip}/{branch,tag,sha}`

 However, based on the file structure of the returned archive, it's not
 clear this is a drop-in replacement, i.e., the top level director is
 `user-repo-sha/`.  So it seems likely that checksums using the existing
 would have to be revisited.

 Alternatively, for GitHub'ers using the v3 API, perhaps just by default,
 could you grant `github.tarball_from` a new `archive` or `v3` option,
 e.g.,
 {{{
 #!tcl
 archive {
   github.master_sites ${github.homepage}/archive/${version}
 }
 default { ...
 }}}

 It may also be possible to query the repo via the API to determine what
 method it used to to provide distfiles, e.g., `gitflow` AVH Edition v3
 items of interest:
 {{{
 "has_downloads": true,
 "archive_url":
 "https://api.github.com/repos/petervanderdoes/gitflow/{archive_format}{/ref}",
 "releases_url":
 "https://api.github.com/repos/petervanderdoes/gitflow/releases{/id}",
 "downloads_url":
 "https://api.github.com/repos/petervanderdoes/gitflow/downloads",
 }}}
 unfortunately, querying `downloads_url` returns an empty set, e.g.,
 {{{
 $ curl -o- https://api.github.com/repos/petervanderdoes/gitflow/downloads
 [

 ]
 }}}
