Twig recently introduced some useful array methods like column (since 2.8.0), filter, map and reduce (since 1.41/2.10.0).

https://twig.symfony.com/doc/2.x/filters/filter.html
https://twig.symfony.com/doc/2.x/filters/map.html
https://twig.symfony.com/doc/2.x/filters/reduce.html

Timber has its own filters pluck and filter. The second one makes native Twig filter unusable.

This would probably introduce a BC break. But would you consider this for 2.0+?
