Mrpack import should consider server files

[Trial97]

looks like modrinth packs should install server mods on modpack creation;

I think there was perhaps some confusion between Modrinth projects and Mrpack files. A Modrinth moderator said that projects should be marked as "unsupported" on the client if they do not affect it.

However - if you think about it, it would make no sense in the modpack format if setting client to unsupported behaved the same way as required. This behaviour also is different to Modrinth's own launcher and documentation.
