Yeah, that was just a typo. I've fixed it. Thanks for calling it out.
In KIP-4, I believe we have 3 types of requests: CreateTopic, AlterTopic and
DeleteTopic. The topic configs are a sub-type of the Create and Alter commands.
I think it would be nice to simply have a AlterConfig command that can alter
any type of config rather than having a specific ClientConfig.
AlterConfig => [ConfigType [AddedConfigEntry] [DeletedConfig]]
ConfigType => string
AddedConfigEntry => ConfigKey ConfigValue
ConfigKey => string
ConfigValue => string
DeletedConfig => string
The downside of this approach is that we will have 2 separate ways of changing
topic configs (AlterTopic and AlterConfig). While a general AlterConfig only
makes sense if we plan to have more than two types of entity configs.. it's
definitely more future proof. Thoughts?

Agree with Jun here on the JSON format. I think your intention was likely
to have actual JSON here and it was just a typo in the wiki?
