native builders of linux-aarch64

### Your question:

There are now options for building natively on Arm within the Azure pipelines and [free Github runners](https://github.blog/changelog/2025-01-16-linux-arm64-hosted-runners-now-available-for-free-in-public-repositories-public-preview/)

Conda Forge is still using a mix of emulation and cross-platform builds to support the 2000+ packages that now have a native linux-aarch64 build.

It would save a lot of time (emulation), and effort (cross-platform builds) - if the defaults could migrate to the new runners or an Arm pipeline.

Has this been considered - are there blockers, or guidance for applying this at the feedstock level?

(note manual attempt to do it is suggested here: https://github.com/conda-forge/conda-smithy/issues/2243)
