Actually I'd say your arguments are the reason they SHOULD do any major changes now. Now they only have a few early adopters and few real customers. They have two futures:
1. They never get real installed base. Who cares if they change anything, dead is dead, so we can ignore this future.
2. They do get a toehold somewhere. At that point your argument would apply, pushing any major change all at once would be a bad idea.
So don't be confused by the 1.0 version number, this is still a developers release now, if they have a hankering to get a big change that didn't make it onto the 1.0 hardware now is probably the last chance, six months from now would be too late, either way.
