I personally don't use any macros in 6502 asm at all - not even things like `add` or `sub` - which are already present in https://github.com/cc65/cc65/blob/master/asminc/generic.mac.

But if someone does a significant contribution that depends on `ldax` or `stax` and therefore adds them to https://github.com/cc65/cc65/blob/master/asminc/generic.mac then this wouldn't be a reason for me to reject the contribution.
