I don't like prefix arg, too.  It feels like prefix arg should change
the user-visible behaviour of the command, and running asynchronously
feels more like a technical detail, though important one.

Maybe there could be rules for find-file to use async behavior by
default, like:

- When a non-local method is explicitly used (that is, not /sudo)

- When default-directory is on a remote host

- When a file being visited is greater than some customizable size

- When a special command was given before (analogy with `C-x RET c' was
already mentioned here).  That special command by default could "toggle
default".  It could accept prefix arg, say C-u for "force sync" and C-u
C-u for "force async".  That way sync/async preference will be decoupled
from the actual command, and could be added to any other command in the
future.
