Honestly you have a different issues here.
One it was never the intent to allow non LG paladins, and this does open the door way to do so. People keep saying well no it doesn't but in fact it does, by the core rules some of your power comes from a god,
Remember that setting specific rules can trump general core rules and other items such as class/feat/etc. availability. All Golarian clerics and paladins are required to be sponsored by a specific diety.
Another thing to keep in mind was that it's very likely that WOTC invented the idea of godless clerics to pacify the "D+D leads to PAGAN AND SATAN WORSHIP!" crowd, probably also for the same reason that the D+D cartoon party did not have a cleric; perhaps not realising that such crowds can't be reasoned with.
Whoa-k. The first part of your post was a very benificial reminder that local over-rides global. Always good to keep in mind.
However, the second part of your post was pure speculation. Be careful what you claim, unless you've got some data to back it up.
(Not trying to hijack the thread...)
On the whole, editing and revisions are a delicate balance. In works such as these, the Paizo folks should always be keeping in mind the (business) tactical and strategic consequences of what their changes mean. I'm sure they are aware of some of the problems besetting WOTC, it's one of the reasons their business has been successfull, by NOT being WOTC. At the same time, opinions and outlooks do change, and I prefer a system that isn't so rigid that it can't, or won't adapt to make itself better.
My guess, based on what I've seen from them so far, is that they'll stick to mostly publishing approved "alternatives" that can be selected, and still remain "canonized" by players. Ultimately, I know most of us prefer something to refer to, but in the end each campaign is our own. So make of yours what you will, just make an effort to inform your players of house rules that deviate from written rules in use, and if you decide that a change in mid campaign makes your game better, consider it, but provide and explanation to the players so they can follow the logic/wisdom of your decision.
