Loading .dir-locals.el is a non-trivial operation, because several
directories must be traversed for existence check of such a file,
starting at the current directory, and navigating up to "/". This might
be time-consuming.

I suspect, this is the reason it has been disabled for remote

One could improve the checks by adding a new file name handler for
searching and loading of .dir-locals.el. This would allow to apply all
checks at once on the remote side, with a better performance.

A similar file name handler was introduced for `vc-registered', which
was improved by a special implementation for remote files.
