Let me clarify. What I have in mind is my proposal about using
org-element for fontification:
https://orgmode.org/list/87ee7c9quk.fsf@localhost

The usage org `org-at-timestamp-p' in multiple places in org.el implies
that Org treats timestamp-like strings as actual timestamps even when
org-element does not recognise them. Then, if, say, I implement a new
fontification system purely relying on org-element, some timestamp-like
strings will remain interactive (for example, using mouse context menu)
but will not be fontified.

Any other idea relying on org-element might also suffer from such
issues.

Is there an easy example demonstrating the potential problem?
For reference, I did try to implement parsing node-property values and
even did not fail any tests, except the one directly checking the
current timestamp-in-property-drawer parsing.

Best,
