Grist forms support uploads since 2025 https://github.com/gristlabs/grist-core/pull/1655

Since it is relevant here: support for uploads was code written by a French contributor, and reviewed by a developer working for the French gov (ANCT/DINUM) and a developer working for Grist Labs. Grist Labs has since maintained and improved on it. The forms feature itself was inspired by an integration built by Camille Legeron at ANCT.
