This is just my 2 cents as my experience with the class is limited to level 7 at the moment. I'm not sure how I feel about a potential Extra Fervor feat.
If it could be taken multiple times, for some builds it might be so good you would just take it for most of your feat slots (like some tanky Paladin builds). While powerful, that may be a bit boring.
Also, the class really seems to be based around the Fervor management mechanic. The feat would remove the decision as to whether you should burn a Fervor or not. At higher levels, the answer would always be "yes".
All that said, I think I would be in favor a feat that could be taken once, like Extra Channel. It would be a must have feat, but not eat up most of your feat slots.

I don't think it is right that there is an "extra channel" and an extra "lay on hands" feat that the paladin can take but not an extra fervor feat. I mean the Paladin can literally have 6 extra uses of Lay on Hands with just two feats. Granted 4 of them must be used to channel but still. . .

A one time only extra fervor feat would not break the character. I mean the Warpreist needs help anyways. It is one of the weakest of the new classes out of the book. I have seen dozens of brawlers, bloodragers, and arcanist in my local PFS but I know of only one other Warpriest besides myself.
I wouldn't say that's because they're BAD. They are, however, extremely complex. They have 4 different class currencies, plus spells, plus scaling damage dice. They have a ton of stuff to keep track of. A lot of people would rather do something way more simple.
As far as Extra Fervor goes, I hoped for one too. It's possible they consider the "fervor for swift spell" too good though, which is why they excluded it. But with the reduced dice on fervor and needing it to buff yourself, I do feel like they need a way to get more. Even if it was a feat you could only take once, I'd be happy.

Looks like it was pretty deliberately left out of the ACG, to me.
Maybe with Advanced Class Origins that is supposed to be coming out reasonably soon, but I sort of doubt it.
To be fair if the feat read something like this
EXTRA FERVOR
Wis 13 Fervor class feature
You gain two extra uses of your fervor ability.
SPECIAL: You can take this more than once.
it would be horribly broken. Even at one it would be extremely strong. Being able to quicken 1 or possibly 2 spells a fight is good. Being able to quicken a spell actually literally every round would probably break the class.
If it can be taken once it should have just been baseline everyone would take it.
As to why it's left out it's really clear that whoever wrote the WP hated it with the with a passion as hot as a thousand suns. They probably finished writing it and were just glad to be off the miserable job.

Why would you allow it to be taken more then once. A one time 2 extra use feat would not break the class. However it would make the class more balanced compared to other classes. Like say Paladin. (Who can gain multiple use of lay on hands feat)
