The loader git currently filters out references considered not that interesting [1]:
- auto-merged github pull requests (reference names starting with `refs/heads` and
finishes with `/merge`)
- peeled refs (reference names finishing with `^{}`)
Nonetheless, the current loader git actually still load pull requests references and
there can be a lot depending on the repository. See for example a recent snapshot on the
torvalds/linux [2] repository.
We should consider whether that's still relevant to ingest those references.
The webapp already considers this noise and has been filtering them out from the
browsing since v0.0.288 version [3]. So that tends toward ignoring them as well during the ingestion.
That should also alleviate other current considerations [4].
