I'm only interested in emulating the published specifications (unless
DEC used undocumented VT bugs when writing it's software).

The main PuTTY bug for me is a keyboard emulation bug.

Unless the keyboard emulation is the strict VT layout keyboard
(where the key functions are mapped to their position on the keyboard
and not to the function as labelled on the PC keyboard) then PF1-PF4
doesn't work unless application keypad mode is active.

As most of the DEC software which uses PF1-PF4 first puts the keypad
into application keypad mode, you don't usually notice this, but for
software which doesn't do this, it's a compatibility issue.

Simon.
