Bug report

In Python 3.10, the re.template function exists and is not deprecated:

>>> import re
>>> re.template('', re.I)
re.compile('', re.TEMPLATE|re.IGNORECASE)

In Python 3.11.0b1 this function is gone:

>>> import re
>>> re.template('', re.I)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 're' has no attribute 'template'

This was removed in b09184bf05 without a depreciation period.
Despite being undocumented, projects actually use this function, see e.g. rpm-software-management/dnf#1827

Please restore this function and deprecate it in 3.11 and 3.12 if you want to remove it in 3.13. (That is how I understand PEP 387, section Making Incompatible Changes.)
