Yes, it's a quite useful feature. For years, via my Capture templates, I've 
been adding a property named :Created: to the properties drawer as follows: 

:PROPERTIES:
:Created:  <2022-03-06 Sun 22:42>
:END:

Now, in 9.5.2, literally hundreds of entries that formerly appeared on the 
built-in Agenda views cannot be easily found. 

Regards to all, 
Tom 

PS The variable 'org-agenda-skip-additional-timestamps-same-entry seemed 
expressly made for my use case, to clean up same-day clutter in entries with a 
TODO timestamp.

What you see in the new Org version is not a bug. Property values are treated 
as plain text by Org.

In the older versions, agenda code did not rely on Org's internal parsing and 
matched timestamps in places where timestamps are not allowed (inside code 
blocks, for example). See

Dear all,

I was unable to find a place in manual describing that timestamps cannot be 
placed inside property values:

>> A timestamp is a specification of a date (possibly with a time or a 
>> range of times) in a special format, either ‘<2003-09-16 Tue>’ or
>> ‘<2003-09-16 Tue 09:39>’ or ‘<2003-09-16 Tue 12:00-12:30>’(1).  A 
>> timestamp can appear anywhere in the headline or body of an Org tree 
>> entry.  Its presence causes entries to be shown on specific dates in 
>> the agenda (see *note Weekly/daily agenda::).  We distinguish:

I personally see allowing timestamps (and links) inside property values as a 
useful feature. Would it be of interest for other users?

In any case, we should probably clarify manual in this regard.

Best,
Ihor
