In delete-selection-mode, <delete> deletes the region, but
its keypad counterpart <kp-delete> doesn't delete the region.
This is what `C-h k <delete>' displays:
<deletechar> (translated from <delete>) runs the command
delete-forward-char, which is an interactive compiled Lisp function in
`simple.el'.
And this is displayed by `C-h k <kp-delete>':
C-d (translated from <kp-delete>) runs the command
delete-char, which is an interactive built-in function in
`cmds.c'.
What could be done:
1. Change `delete-char' to delete the active region (might need a poll
since I recall some disagreements about this default).
2. Bind <kp-delete> to the same command `delete-forward-char'
as for <delete>.
3. Add `delete-char' back to delsel.el since typing `C-d' is handy
anyway to delete the region.

Shouldn't `kp-delete' be remapped to `delete'?

It is mapped to ?\C-d in local-function-key-map (if
normal-erase-is-backspace).

Oh, right, now I remember: we don't apply function-key-map repeatedly so
if we have a remapping from kp-delete to delete, it's not combined with
the mapping from delete to deletechar.
I installed the patch below instead which should fix the problem.

Thanks. I discovered another case: in delete-selection-mode it's handy
to select the region of unnecessary shell output and delete with <delete>
(without putting to the kill ring). But now neither <delete> nor <kp-delete>
delete the active region in shell. comint.el has these lines:
;; The following two are standardly aliased to C-d,
;; but they should never do EOF, just delete.
(define-key map [delete] 'delete-char)
(define-key map [kp-delete] 'delete-char)
It seems `delete-char' needs to be replaced with `delete-forward-char'
like in their global bindings? The comment is also wrong because
globally [delete] and [kp-delete] are not aliased to C-d now.

Indeed.
