Hello. In a scratch buffer containing some text, run the function
xref-revert-buffer. The buffer content will be deleted and it is not
possible to undo. The function should check that it is applied in a
suitable buffer before modifying the buffer.
In GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, X toolkit, Xaw3d scroll
bars)

Thanks for the report. Indeed, it sounds unfortunate, if you just called
the command accidentally.
I've pushed a fix (which will make it complain with (void-function nil)
instead of erasing the buffer) to master. Sometime later, we'll tag a
new release of the xref package, and you'll be able to update to the new
version through 'M-x list-packages'.

Should this be backported to the emacs-27 branch?

Why not.
Backported, thanks.
