We are using modify string from external source where we have one field for it. Basically we do
$date->modify($modString)->format().
If my use case is not supported, I can explode the modify string and call modify() multiple times,
but if there is currently a way to write "15th day of -2 months" please let me know.
"first day of" works, so to be consistent "nth day of" should work too

what's wrong with two modify calls? It will allow you to do as many modifications as you want,
I don't see how this qualifies as a bug. This works fine:
$d = new \DateTime('2020-03-28 12:00:00');
echo $d ->modify('first day of -2 months')
->modify('+15 days')
->format('j.n.Y');

Description:
------------
Is it currently possible to use multiple modifications to a date like "first day of -2 months,
+15 days" in one modify() call?
Is it currently possible to to write one modify for "15th day of -2 months"?
Test script:
---------------
$d = new \DateTime('2020-03-28 12:00:00');
// first day of the month, ok
echo ((clone $d)->modify('last day of -2 months')->format('j.n.Y')) .
"\n";
// 15th day of the month - not working
echo ((clone $d)->modify('first day of -2 months, +15
days')->format('j.n.Y')) . "\n"; // bad result
echo ((clone $d)->modify('15th day of -2 months')->format('j.n.Y')) .
"\n"; // not parseable modify string
Expected result:
----------------
31.1.2020
15.1.2020
15.1.2020
Actual result:
--------------
31.1.2020
31.1.2020
Warning: DateTime::modify(): Failed to parse time string (15th day of -2 months) at position 0 (1)
Fatal error: Uncaught Error: Call to a member function format() on bool
