Its more about data interchange support, i.e. we could support GraphML instead/next to the RDF varieties. But this would be difficult for us to generate in a streaming way.

Then for our end users, we would need to hack in a namespace convention to avoid issues when integrating our data.

Then TinkerPop misses the SERVICE concept for federated querying in SPARQL1.1, which is essential for our endusers who do knowledge discovery (i.e. small biology labs without the inhouse capability of running their own large databases).
