Hmm, it seems a bit late to ask for changes. Unless there are
developers which plan on shipping PowerPC-only apps that require
10.5 and up (and need to detect that they are on Intel)? That
seems like a small market to me :)
I agree that Gestalt would have been cleaner, but I kind of think
that ship has already sailed...
It's never too late to ask. ;-) In any case, Apple still sells
PowerPC models. Even though I expect everything will be Intel by
the time 10.5 ships, that's not at all the same as saying everyone
will be using an Intel-based Macs right away, so a lot of
developers will probably be supporting both processors for a while
to come. Transitioning the hardware base is going to take even
longer than transitioning the OS, and look how long it took Mac OS
X to really overtake Mac OS 9.
This is a simple thing to implement, so there might be hope.
In this particular case, changing the value of an existing Gestalt
selector would break binary compatibility with existing
applications. While having a new Rosetta-specific Gestalt selector
might be useful, that requires explicit adoption in the same way as
the sysctl does and it doesn't add much value over the sysctl. Which
isn't to say that it won't happen -- it isn't my decision -- but I
think it's unlikely.
