The contract with the SB API is that changes are only additive. So you only need to track versions if there's an API that was added at some point, and you want to make sure you have a version of the headers with that API. In practice that means you shouldn't need to keep updating the SB API's you are building against. The version that has the all API's you are using will always work against lldb's newer than when that API was added. That is, until we decide to do a SB API v. 2.0, but we'll make the same guarantees about that one, since it isn't that hard to do and makes life much simpler for everyone.
At some point, we were thinking about having an SB API versioning scheme which would allow you to detect whether the API's you are building against has some new API's (see include/lldb/lldb-versioning.h) But I don't think we ever added the necessary annotations. Presumably there wasn't any clamor for them, but I don't actually remember the story there. Greg might have more history...
