uni-id-pages 中 login-by-weixin.js 文件为什么要限制weixinPlatform !== 'mp'？？

uni-id-pages 中 login-by-weixin.js 文件为什么要限制weixinPlatform !== 'mp'？？这些信息不应该只有微信登录才能获得的吗？详见下面源码。按照这个逻辑，貌似微信小程序登录还是注册都永远不能满足if条件。

if (type === 'register' &&** weixinPlatform !== 'mp'**) {  
    const {  
      nickname,  
      avatar  
    } = await weixinApi.getUserInfo({  
      accessToken,  
      openid  
    })  

    if (avatar) {  
      // eslint-disable-next-line n/no-deprecated-api  
      const avatarPath = url.parse(avatar).pathname  
      const extName = avatarPath.indexOf('.') > -1 ? url.parse(avatar).pathname.split('.').pop() : 'jpg'  
      const cloudPath = `user/avatar/${openid.slice(-8) + Date.now()}-avatar.${extName}`  
      const getAvatarRes = await uniCloud.httpclient.request(avatar)  
      if (getAvatarRes.status >= 400) {  
        throw {  
          errCode: ERROR.GET_THIRD_PARTY_USER_INFO_FAILED  
        }  
      }  

      const {  
        fileID  
      } = await uniCloud.uploadFile({  
        cloudPath,  
        fileContent: getAvatarRes.data  
      })  

      extraData.avatar_file = {  
        name: cloudPath,  
        extname: extName,  
        url: fileID  
      }  
    }  

    extraData.nickname = nickname  
  }
