I just tested it with IBKR and was able to create a call buy order (exp 1/29, $500 strike) for a single contract. Info: Market was closed so the order wasn’t executed but it was accepted by the order system before i cancelled it.

I have a message: "Transactions in this instrument are limited to closing-only trades" @ Jan29'21 300 CALL GME.

  You’re right. I get the same message for Jan 29’31 300 CALL but do not get the message for the $330 or $500 strike. Looks like its only for ITM strikes.

    This is sad indeed :(

I don't know IBKR's system, but most OMSs will accept an order unless it's blatantly wrong such as invalid stock. It's the execution engine that really enforce the rules.

Tested IBKR today - I was able to place a simple Limit order for GME stock which was good till close but when I refreshed to view my list of orders it shows as Cancelled. Tried it twice, did the same thing each time.
