Of course.  And if there are doubts as to when and why Eglot's
"Package-Require"'s are updated, one can always M-x vc-region-history
on that single line of lisp/progmodes/eglot.el.  For example, recently
Xref requirement was bumped because:

      Work around package.el transitive dependency bug

      Eglot already depends transitively on Xref 1.4.0 via Project,
      but package.el doesn't pick up on this in Emacs 28
      (which has Xref 1.3.0).

      * lisp/progmodes/eglot.el (Version): Bump to 1.11.
      (Package-Requires): Explicitly require Xref 1.4.0, which is
      the version already required by Project, for the benefit of
      Emacs 28 (bug#61048).

If you find some dependency is set unnecessarily too high, I
don't see any problem in downgrading it.
