Hi,

Well, yes, I consider this a poorly considered “feature”, or arguably
a bug, for exactly the reason you said, they are local to connections
and machines, and thus highly variable.

Not really. They exist for the reason that a user can override the
default values offered by Tramp. This I would call a user option.

Tramp has a lot of further host specific data, which are all kept in
variables.

We can probably argue whether this is a bug in tramp or a bug in
customize-save-variable tho (why on earth does the act of saving a
single variable value saves all customized values if a custom file
exists?)

I agree with the latter.

Best regards, Michael.
