The specs say nothing about for which purpose commands are intended.

Well, according to this document:
Quote:
info
the engine wants to send infos to the GUI. This should be done whenever one of the info has changed.
The engine can send only selected infos and multiple infos can be send with one info command,
e.g. "info currmove e2e4 currmovenumber 1" or
"info depth 12 nodes 123456 nps 100000".
Also all infos belonging to the pv should be sent together
e.g. "info depth 2 score cp 214 time 1242 nodes 2124 nps 34928 pv e2e4 e7e5 g1f3"
I suggest to start sending "currmove", "currmovenumber", "currline" and "refutation" only after one second
to avoid too much traffic.
(...)
* currmove
currently searching this move

So, the purpose of the "info" command is merely to provide the user with information, e.g. about the move currently being searched. It is certainly not intended to provide the GUI with a list of legal moves.

Sure you can tell me that you don't care what the protocol author thinks you should do with the information you get. However, relying on behavior not required by the protocol is simply broken.

For regular chess your problem is easy to fix: just let the GUI generate the legal moves. You can then use any info you get from the engine to improve the sorting of moves or whatever. If you don't get that information in time, then so be it.

For variants, I am sure engine authors will want to accomodate for your wishes. Just come up with a proper protocol extension that does what you need.
