[OE-core] is there ever a compelling reason for "FILESEXTRAPATHS_append := ..."?

[Robert P. J. Day]

  occasionally, i run across an existing bbappend file which contains

  FILESEXTRAPATHS_append := ...

and that makes me nervous as i don't see the rationale in *appending*
to that variable in a bbappend file -- seems to defeat the purpose of
potentially overriding what's in the original .bb recipe.

  now, sometimes it's obvious that it's broken as i'm currently
looking at an example:

  FILESEXTRAPATHS_append := "${THISDIR}/${PN}:"

which makes no sense at all with the colon at the end. but other than
something so clearly broken, are there situations to append to
FILESEXTRAPATHS? that just seems counter-productive, but maybe i'm
missing something.
