I have realized that "first wins" parsing principle (consider +a =b+ 
c*d=) may mean a problem for timestamp at the end of link text. So

     [[file:test.txt][Test [2023-01-28 Sat]]]

requires a zero-width space after the bracket closing the timestamp. The 
same is applicable to fuzzy link to headings. So either

     [[*Heading \[2023-01-28 Sat\]][Heading [2023-01-28 Sat]​]]
ZWS in between--------------------------------------------^^

or

     [[*Heading \[2023-01-28 Sat\]]]

should be used. `org-insert-link' handles it correctly, but when typing 
links from keyboard, users should be aware of such kind of pitfall. So 
timestamps in headings may be source of some inconvenience.

May it happen that in some old Org version timestamps at the end of 
headings were removed due by code intended to handle statistics cookie 
[1/10]?
