Is kuzushiji considered archaic?


I am wondering if it is a necessary skill to learn how to read and write
kuzushiji in modern japanese.




Moderate _kuzushiji_ style based on modern orthographical standard (like
[this](http://pds.exblog.jp/pds/1/201001/01/47/b0172747_19595829.jpg) or
[this](http://blog-fino.cocolog-nifty.com/photos/uncategorized/photo_23.jpg))
is widely accepted and well understood. Some people are actually fond of
writing in such style, so maybe you'll need to learn how to read them in
private letters and fancy cards.

Meanwhile, hardcore historical _kuzushiji_ stored in archives and museums
(like [this](http://su-cultural-history.up.n.seesaa.net/su-cultural-
history/image/P1030717.JPG?d=a48) or [this](https://ks.c.yimg.jp/res/chie-
que-10135/10/135/309/910/i320)) is totally different and basically
incomprehensible to today's people without proper training. Students of
Japanese history or philology have to start with learning to decipher those
characters. They are, like old German handwriting, definitely archaic.
