Filter entities globally?

According to the docs, filtering identity providers is possible per SP.

We have 100s of SPs, and now I'm looking for a way to show a specific IdP only for a few SPs.

The only way I could make this work was by applying a snippet to those few SPs:

  'discopower.filter' => [
      'tags.include' => [
         'all'
      ],
      'entities.include' => [
          'https://needle.idp',
      ],
  ],

and then on every other SP excluding it:

  'discopower.filter' => [
      'entities.exclude' => [
          'https://needle.idp',
      ],
  ],

As said this works but a bit cumbersome as I'd have to make sure this will be there for each new SP etc.

Would it makes sense to be able to supply such a config at a higher level, for example in saml20-idp-hosted.php or some other place?

从 docs/discopower.md 中的过滤部分开始，将其中按 SP 配置的内容与提议的 saml20-idp-hosted.php 位置进行比较。跟踪每个 SP 的 discovery 过滤器是如何加载的，并确定可以在哪里应用更高层级的设置。当无需向每个 SP 添加代码片段即可全局配置所需的 IdP 可见性时，即表示完成。
