[arch-dev-public] Using SPDX License list as identifiers

Hi This just came up on IRC. Thoughts on using the SPDX license list as valid license identifiers for all packages? https://spdx.org/licenses/ Most of the identifiers would change but we would have a consistent and much larger, externally-maintained list to choose from. It would also be a little more accurate; eg. the SPDX allows for distinctions such as "LGPL-3.0-or-later" vs. "LGPL-3.0-only". We could retain the current identifiers as symlinks. J. Leclanche
