This is intentional. PR #4474 is also still relevant, because it is a change specific to includes
(not normal file reads).
UPGRADING currently only mentions this change for fread() and fwrite() in particular, but of course
it also affects many, many other filesystem functions that read/write internally. I don't think
we want to exhaustively list everything that might be affected.

Well, the behavioral change has been introduced with commit
1cbcf0f[1]; not sure whether this particular behavior has been
anticipated. If so, PR #4474[2] appears to be superfluous now.

This is not particularly related to hash_file(), but also affects
other filesystem functions, see <https://3v4l.org/5XQB3>.
IIRC,
that was a very deliberate change/fix.

Description:
------------
See https://3v4l.org/58RgW
Until 7.4.0beta1, it returned string(32) "d41d8cd98f00b204e9800998ecf8427e" and since
7.4.0beta2 it displays a notice.
Notice: hash_file(): read of 8192 bytes failed with errno=21 Is a directory in /in/58RgW on line 3
On Windows there is no notice, and it only returns false. I'm only creating this issue as I
don't see anything in upgrading notes, deprecated features or the changelog about it.
Test script:
---------------
<?php
var_dump( hash_file( 'md5', '/etc/' ) );
