Smit was reacting to a suggestion that the national side might embark on a strike if the squad was tampered with politically.
Earlier this season SA Rugby president Oregan Hoskins forced coach Jake White to include Luke Watson in the side amid political dissatisfaction with the Springboks' racial make-up, while this week South Africa's head of the Parliamentary Committee on Sport, Butana Komphela, said the number of black players expected to be picked - six - was "not good enough".
Smit did not deny any strike action, but was coy when discussing details at this stage, according to The Times newspaper.
"It would be hard for me to comment on that now - we need to see what the squad looks like and hope sanity prevails.
"If the best 30 players are picked, it doesn't matter who it is. Then, I think, the players will be happy."
Meanwhile, Hoskins believes the Springboks should develop their own haka before major international games.
Hoskins was reacting to suggestions from White that the side had thought of reviving a Zulu war dance as a challenge before games.
"This will enable us to use something from the unique culture of South Africa, whether Zulu or Xhosa or whatever, and to make it part of rugby," Hoskins told Afrikaans language Beeld newspaper.
"It would also provide an opportunity for a large part of the population to identify more strongly with rugby."
White revealed his team had already performed the ritual in the changing room but claimed it could have a greater impact on the pitch.
In 1928, when South Africa played New Zealand in a series of four Tests, the Springboks performed a "war dance" as a counter to the haka before every match.
Hoskins said: "I would certainly be in favour of discussing it. The All Blacks certainly derive a psychological boost from their haka.
"I was watching Jannie du Plessis before last week's Test in Christchurch. When the All Blacks performed their haka, one could see he was itching to do something similar."
