The features mentioned above are of version proto3 and of editions 2023 and 2024. At this moment proto2 is not supported by Embedded Proto. With regard to proto2 support google states the following:
Prefer proto3 while proto2 will continue to be supported, we encourage new codes to use proto3 instead, which is easier to use and supports more languages.
For this reason, it is unlikely that Embedded Proto will support proto2 in the future.
