Of course I use yank-excluded-properties!  But manually tweaking that
variable each time I intend to yank some text (which would require
first to find out which properties are in that text) is much less
convenient than typing "M-o M-o", don't you agree?  And adding face
properties permanently to yank-excluded-properties would get in the
way of the use cases where I do want faces to be copied.

Btw, the "without font-lock-mode active" part is not the situation I
was talking about.  Remember: global-font-lock-mode is now t by
default, so bumping into a buffer where font-lock-mode isn't active is
quite hard...
