I was looking at adding some grommets to my solar cover (maybe brass)
Is there a downside to this regarding chemical reactions with the chlorine?

Chlorine will attack virtually any metal. Even stainless in the right concentration.
I am pretty sure my pool light has brass conduit running to it. I thought the PB did it because brass stands up better to pool water?
I'm thinking it might be alright in my situation, since the only time it would really be touching chlorine is when the cover is rolled onto the reel, otherwise the grommets would be up out of the water. Hrm.
Back in the day, brass hardware was commonly used in pool equipment. Before the plastic butterflys, brass bolts and wing-nuts held your attachments to your pole. Brass ball floats held up the the rubber vac hoses that could not float on their own. Of course, with no CYA, FC was normally 1-3ppm. I think they will hold up just fine.
I probably should've qualified what I said. In pool concentrations, I think brass will function just fine. It'll corrode very, very quickly but it will not be unusable. If you don't mind the look, I would use it.
It looks like my main drain cover has brass screws and I don't see any corrosion at all (?) Is there something like "marine grade" brass that maybe there are?
loop-loc cover anchors are brass they weather well, but they are just near the pool not in it
Brass is an alloy of copper and zinc. The rate of corrosion is higher when the percentage of zinc is higher. Keeping the zinc below 15% and adding a small amount (1%) of tin can make the brass more resistant to corrosion as described here.
