Questions about "Scopes per API" limit

Oh!? The other post I have shared reference to, says there is no documented limit for how many scopes can be defined per API.

I was hoping to define basic entity level permissions and then define permissions to limit access by groups.
For e.g.
Entity level permissions : create:posts, delete:posts, list:posts
Grouping permissions : board:some-board-1, board:some-board-2board:some-board-n
A user (X) can have have permissions like this : create:posts, delete:posts, list:post, board:some-board-2, i.e. X can manilulate posts on some-board-2.
Clearly, the number of boards will exceed 1000, exceeding the limit for permissions per API
