Not when package dependencies are involved.  If you weren't aware,
in Emacs 26 (including 29), if you explicitly ask to install package A
and it depends on :core package B, which you didn't ask to install,
package B gets upgraded.

In another data point, the last two patches I proposed to package-install
are similar and only extend the "upgrade-even-if-:core" behaviour
to two packages that weren't core are now :core.  Those two packages
are Eglot and Use-Package.  The rationale I used to develop these patches
was to protect users like you (inasmuch as Emacs 28 already protects
you) _and_ to protect Eglot users.  I am of course presuming that
you aren't/weren't also an Eglot user, otherwise you would have been
hit by these package upgrades related to dependencies in Emacs 28
and would have noticed them.
