I disagree with your disagreement, and agree with Michael here.  I see
no maintainer's complexity in using file-name handlers that could be
avoided by not using them: file-name handlers are, and will always be,
an integral part of Emacs internals, so thinking about them as
"complexity" makes no more sense than, say, thinking about GC as
complexity.

P.S. Would people please not use "shorthands" like "f-n-h-a" and
"a-s-p", but instead use the full names?  Those "shorthands" make the
text harder to read, while OTOH typing them in full using M-/ is very
easy and takes only a couple of keypresses.
