I've changed find-file-asynchronously to accept also a regexp as
value. If you customize

(customize-set-variable
  'find-file-asynchronously tramp-file-name-regexp
  "Visit remote files asynchronously")

you get the requested behavior. The default shall still be nil, I
believe.

If needed, we could also allow a function as find-file-asynchronously
value. People could add their own checks then, like for file name size.
