So that would mean that I need to implement an own 
flowable for internal links? This because - for example
in Paragrap(), it only has its API which doesn't allow 
manipulating canvas directly and it's inline markup doesn't seem
to have this internal link creation feature. Am I right?

Well, it would not make much sense anyway to add the support
into Paragraph as link would just jump from part of the document
to another and scrolling typically only happens vertically, 
so it could very well be an own flowable.

Have you already implemented such, planned to do so or if someone
manages to do such beast, will you inlcude it to the distribution?
canvas.py seems to have bookmarkPage method and as it really doesn't 
require much wrapping or splitting, it could be easy to do.
