I understand, but why is this an issue in Yocto project ? The maintainer
does not use tags and git describe is fast useless.

You should contact layer's maintainer and ask for that. Anyway, outside
poky, tags are quite unused in layers.

It is clear that a tool to maintain the layers in sync is required, but
it is quite independent how the layers (and many are proprietary layers)
are built. So you can use "repo" or "kas" (my preferred one) for that.
