Update. After a couple of snafus with the counter/sink installation, I was FINALLY able to get my kitchen faucet hooked up this morning. It's been 27 days since it was disconnected. But running water at last!
If the sink installers hadn't mounted brackets where the faucet plumbing was supposed to go, I could have had water a week ago. If they installers had mounted the sink when they did the countertops, I could have had water two weeks ago. I'm SOOOO glad it's all done now.
