I'm not seeing a way to csv manufacturer attributes.... am I missing something?

There's no feature for that but Mike does offer an add on - https://www.dlss.ca/proddetail.asp?prod=QuickAttributes

We are using that mod from Mike, It does not offer a csv function but it is a very nice addon as it gives a really nicely laid out listing of all the attribute options at the bottom of the admin product edit page so you do not have to mess with the ECT built in cumbersome quick dropdown feature.
