Request: Review pending neuroimaging PRs (#7886 BIDS loader, #7887 lazy loading)

[The-Obstacle-Is-The-Way]

Summary

I'm building production neuroimaging pipelines that depend on datasets and would benefit greatly from two pending PRs being reviewed/merged.

Pending PRs

PR	Description	Status	Open Since
#7886	BIDS dataset loader	Open	Nov 29
#7887	Lazy loading for NIfTI	Open	Nov 29

Use Case

The neuroimaging community uses the BIDS (Brain Imaging Data Structure) standard for organizing MRI/fMRI data. These PRs would enable:

1. feat(bids): Add BIDS dataset loader for neuroimaging data #7886: load_dataset('bids', data_dir='/path/to/bids') - Load local BIDS directories directly
2. fix(nifti): enable lazy loading for Nifti1ImageWrapper #7887: Memory-efficient NIfTI handling (single 4D fMRI file can be 1-2GB)

Current Workaround

Without these, users must either:

• Upload to Hub first, then consume (works but slow iteration)
• Hand-roll BIDS parsing (duplicates effort)

Request

Could a maintainer review these PRs? Happy to address any feedback. The BIDS loader has tests passing and was end-to-end tested with real OpenNeuro data.

Thank you for the great work on Nifti() support - these PRs build on that foundation.
