Description:
------------
Actually, DateTimeImmutable is not usable everywhere DateTime is.

Missing support I have found is:
* DatePeriod::__construct where end parameter does not allow a DateTimeImmutable objet as date_ce_date is used instead of date_ce_interface
* intl extension (see grep -rn php_date_get_date_ce ext/intl for complete list) which use the function php_date_get_date_ce (so date_ce_date)

Test script:
---------------
var_dump(datefmt_create('fr_FR')->format(date_create_immutable('1970-01-01')));

$start = new DateTimeImmutable('last monday');
var_dump(new DatePeriod($start, DateInterval::createFromDateString('1 day'), $start->add(DateInterval::createFromDateString('5 days'))));

Expected result:
----------------
string(39) "jeudi 1 janvier 1970 00:00:00 UTC+01:00"

object(DatePeriod)#3 (6) {
...
}

Actual result:
--------------
Warning: IntlDateFormatter::format(): datefmt_format: object must be an instance of DateTime in %s on %d

Fatal error: Uncaught exception 'Exception' with message 'DatePeriod::__construct(): This constructor accepts either (DateTimeInterface, DateInterval, int) OR (DateTimeInterface, DateInterval, DateTime) OR (string) as arguments.' in %s:%d

This has been fixed in 5f09944662e09ea0b3f93cfab8702f188955e68c which is in 5.5.9 and later.

The commit you mention seems to allow DateTimeImmutable usage with DatePeriod::__construct but still does not fix intl stuffs.

Test script:
---------------
ini_set('intl.error_level', E_WARNING);
var_dump(
        datefmt_create('fr_FR', IntlDateFormatter::FULL, IntlDateFormatter::FULL)->format(date_create_immutable('1970-01-01')),
        datefmt_create('fr_FR', IntlDateFormatter::FULL, IntlDateFormatter::FULL)->format(date_create('1970-01-01'))
);

Actual result:
--------------
Warning: IntlDateFormatter::format(): datefmt_format: invalid object type for date/time (only IntlCalendar and DateTime permitted) in %s on line %d
bool(false)
string(39) "jeudi 1 janvier 1970 00:00:00 UTC+01:00"

Expected result:
----------------
string(39) "jeudi 1 janvier 1970 00:00:00 UTC+01:00"
string(39) "jeudi 1 janvier 1970 00:00:00 UTC+01:00"

DateTimeZone::getOffset also doesn't accept a DateTimeImmutable object.

I'm getting the issue that formatting a DateTimeImmutable with IntlDateFormatter results in an empty string.

On PHP 7.3 Intl still does not support DateTimeImmutable with formatObject:

>>> var_dump(datefmt_format_object(date_create_immutable('1970-01-01'), 'fr_FR'));

PHP Warning:  datefmt_format_object(): datefmt_format_object: the passed object must be an instance of either IntlCalendar or DateTime 

One still has to use the long form:

>>> var_dump(datefmt_create('fr_FR',NULL,NULL)->format(date_create_immutable('1970-01-01')));
string(42) "jeudi 1 janvier 1970 à 00:00:00 UTC+01:00"
