Two other questions:

Should there exist a mechanism to give the parsers access to the whole 
buffer (IOW, to let them ignore both the bounds passed to 
'treesit-make-parser' and the restriction set by the user)?

And of course, the bounds given to 'treesit-make-parser' should become 
markers, right, that is, their position should change whenever the buffer 
contents change, right?
