Can't we cater to both cases by adding lisp/term/ghostty that reused
the parts of xterm.el which work fro Ghostty?  I think this should be
more robust and future-proof than just the alias.  Since Emacs has a
general machinery to cater to specifics of each terminal, it sounds
not very clean to provide an alias, when "Ghostty is not de jure a
xterm variant".  Or what am I missing?
