Emacs 28 ships with Xref 1.3.0, and without Eglot.  Eglot depends on
Project 0.9.3 directly and on Xref 1.4.0 transitively.  Yet package.el
for some reason deems that the built-in Xref 1.3.0 satisfies this
requirement, and does not pull a more recent version from GNU ELPA.

[ BTW, there is nothing special about steps 1, 4, 6 in the recipe above:
  they just demonstrate that the expected version of Xref is missing. ]

At first glance this sounds like a package.el bug, but since there won't
be an Emacs 28.3, and until someone checks whether it's present in Emacs
29+, perhaps something like the following is needed as a workaround?

I'm okay with this installed on emacs-29, unless Dmitry or João have
better ideas or objections.

AFAIU, the change Basil proposed is exactly meant to help package.el
DTRT here.  It needs this information about dependencies to be
accurate.

It should have this information already: project 0.9.3 depends on xref 
1.4.0.

That dependency version goes as far back as project 0.8.3.

I thought Basil explained this: it's some bug in package.el from Emacs
28.
