Flexinode limits

I post into the pre-installation forum, however nobody answered.

The presentation text of flexinode is : Flexinode is a module that allows non-programmers to create new node types (flexible content types) in Drupal when their needs are MODEST.

What does "modest" mean?
Is there a functional limit to manage data compare to dedicated module?
Is there a limit to the number of created nodes (e.g. number of lists) ?
Is there a practical limit to the number of data per node or list (thousands, more) ?

What's your experience? Thanks to you for your advices., and possibly precise the term in the presentation text.
