The issue _is_ with defvaralias, but it's only a problem for user
options, things that might be set in .emacs before the associated
alias definition is evaluated. It's hard to see why there should be
non-obsolete aliases to user options, it just causes confusion. I
think there would be false positives if the warning was associated
with defvaralias, which is mostly used with non-user-options, I would
think.
The last time a similar issue came up, Stefan preferred that only
define-obsolete-variable-alias be changed; see
