Indeed. However, I've never heard about such a situation all the years
I'm using Tramp. And there is still the backup file which could be moved
back, isn't it?

Maybe. But there are also other dangerous commands in  Tramp, which must
be protected then. Isn't this overcautious?

There are situations, Tramp cleans up its whole cache (for example, when
a connection has been broken). And there are the `tramp-cleanup-*'
commands, which give the user the same mean, interactively.
