Comment # 5 on bug 1192248 from Neil Rickert

I am not persuaded that this makes any sense.

Traditionally, such user executables have been in "$HOME/bin", and that is on
the default path.  That tradition existed before "freedesktop.org", and even
before linux existed.

I occasionally find it useful to:

rm -rf .local .config .cache

so that the next login will reset my desktop back to default settings.  I do
not want to delete user executables when I do that.
