Nuget packages after 172.52.0 do not support netstandard2.0

I tried using the most recent version (172.64.0 at time of writing) in a netstandard2.0 project, and it failed to restore. I suspect that's because 172.64.0 doesn't explicitly support netstandard2.0.

Version 172.52.0 is the newest version that works. Was removing support in later versions deliberate? If it was, what is the intended way forward for people using SMO in netstandard projects? If it wasn't deliberate, is there any chance of getting a new version out that does support it (even if it's just versioned as 172.64.1 or 172.64.0-netstandard or something, with no changes from the current 172.64.0)?

I don't think there's any particular bits in 172.64 that I need right now, so using 172.52 isn't a showstopper, but I do like to keep my references up-to-date as far as I can.

バージョン 172.52.0 と 172.64.0 の NuGet メタデータおよびターゲット フレームワークを比較し、その後 netstandard2.0 プロジェクトで restore を再現します。完了条件は、サポートが意図的に削除されたかどうかを確認し、そのうえで後続のパッケージで netstandard2.0 互換性を復元するか、影響を受けるユーザー向けの意図された対応方法を文書化することです。
