SPI_connect, SPI_connect_ext return type

Hi, hackers! If you look at the code in the src/backend/executor/spi.c file,
you will see the SPI_connect function familiar to many there, which
internally simply calls SPI_connect_ext. The return type is int, at the end
it says return SPI_OK_CONNECT;
It confuses me that nothing but OK, judging by the code, can return.(I
understand that earlier, before 1833f1a1, it could also return
SPI_ERROR_CONNECT). Therefore, I suggest making the returned value void
instead of int and not checking the returned value. What do you think about
this?
