The crucial point is tramp-default-proxies-alist. If
tramp-save-ad-hoc-proxies is non-nil, an updated version of that user
option is saved in your ~/.emacs file, including ad-hoc definitions.

And if you share .emacs like you do it with your bookmarks, there is no pain.

There is a reason that ad-hoc multi-hop file names are called ad-hoc:
they are ad-hoc, cand not designed to survive an Emacs session.

For example, Tramp supports a use case (requested by Tramp users), where
a container with the very same name exists @work on a remote machine,
and @home on another remote machine. Tramp supports this scenario, you
can always access this container as "docker:container-name:". See
section "6.4.1 Using different proxies for the same destination" in the
Tramp manual. If the extended multi-hop file name would be saved in your
bookmarks (or recentf) file, this doesn't work.

Best regards, Michael.
