You're describing the situation in terms of theoretical user results, but
that's not how the code works, obviously. At some point, the code checks
the user's value of use-package-vs-prefer-newest, sees whether it's the
default or has been customized, and decides to fetch the new package
contents or not. My rough understanding is, *in the non-VC case*, it
downloads new archive-contents for the (each) entire archive regardless,
and then I'm guessing that it currently uses the setting to determine
whether to get a new version or not.
I don't know how the code path in the (use-package :vc) works, but
presumably there's a clear point where the two behaviors (that is,
vc-use-package's supposed former update-by-default versus use-package :vc's
...prefer-newer 'nil lack of update) diverge. I'm asking if there's a
reasonable way to change the default behavior from the supposed-old
yes-update and the current default wait-for-Package-version into something
that leaves the package alone but warns the user, perhaps via *Messages*.
Put another way, your concern seems to be that people might not _realize_
that they're "stuck" on an older Package-Version revision. The alternative
package "manager" code for emacs suggests that there is desire both for
version pinning and direct-from-vcs-packages, so it's likely that there are
users who prefer both alternatives, and emacs is often default-conservative
in such matters, but it seems like it might be possible to have use-package
do a little extra work in the default case to address the "not realize"
part, rather than changing the updating behavior itself.
Hope that helps,
~Chad
