Do we care, given DSA is now legacy and unapproved for most usecases?

Unfortunately, with Microsoft Go we need to implement some legacy algorithms using CNG/OpenSSL because of how Microsoft's internal crypto policy and our fork's high compatibility goals interact. We don't think that this is something every fork needs to do, but we need this support in the library for our own fork.

It isn't a top priority for us at the moment, but it's something we currently do think we need to get done eventually.

Some Q's because I don't understand Go that well :-) and some suggested nitpicks.
