Deprecate python-dateutil

Summary

Python-dateutil is an extension to the standard Python datetime features, widely used by a lot of other projects. However, upstream is unmaintained and possibly with unaddressed security issues. The plan is to try to continue packaging until feasible, but mark the package as deprecated in Fedora and try to convince other dependent project to switch over from it.

However, upstream is unmaintained and possibly with unaddressed security issues. The plan is to try to continue packaging until feasible (it is currently FTB with Python 3.15), but mark the package as deprecated in Fedora and try to convince other dependent project to switch over from it.

Benefit to Fedora

Raise attention to unmaintained and possibly unsecure package and try to move away dependent packages from it.

Scope

• Proposal owners:

Mark package as deprecated.

• Other developers:

Optional: get in touch with other dependent packages upstream and raise attention to python-dateutil package status, asking them to move away from it.

• Release engineering: #Releng issue number

• Policies and guidelines: N/A (not needed for this Change)

• Trademark approval: N/A (not needed for this Change)

• Alignment with the Fedora Strategy:

Upgrade/compatibility impact

While we'll try to fix the FTB with Python 3.15 to avoid breaking dependent packages, we don't want to continue patching the project downstream, so we'll likely orphan the package when the burden gets too high.

Early Testing (Optional)

Do you require 'QA Blueprint' support? Y/N
