Note that the pckbd_keydesc_us keymap maps the scancode of the <- key to

    KC(14),  KS_Cmd_ResetEmul, KS_Delete,

i.e. 0x7f (^?).

terminfo is obviously incorrect here.  Amazingly, the bug is actually
in vt220 description!  wsvt25 just inherits from it:

$ infocmp -1 vt220 | grep kbs
        kbs=^H,

I checkeed termcap.src from netbsd-4 and it's wrong there too.  I have
no idea htf that could have happened.
