Are advisories from different data sources (e.g. GitHub Advisory DB & NVD) merged / combined?

[Marcono1234]

Take for example https://osv.dev/vulnerability/CVE-2019-11932
I have submitted improvements for the GitHub Advisory DB in github/advisory-database#5162. In case this PR is accepted, will this change be included in osv.dev as well, or would it be necessary to contact NVD (which seems to be more cumbersome) since that is currently listed as "source"?
Or for the GitHub Advisory DB, does this also depend on whether the advisory is "github-reviewed" or "unreviewed"?

In case there is no automatic merging / combining happening yet, would it make sense and be possible to add this at least for non-conflicting data? For the example above, my change adds an affected array entry and affected was previously empty.

Maybe related to #2465?

You'd have to get this fixed in NVD separately unfortunately.

OSV doesn't combine or merge any advisories from any sources today. It just acts as an aggregator of distinct sources.
