Just a check-in from the Python Software Foundation regarding the Travis-CI plan that supports s390x, ppc64le, Arm64, and AMD64 architecture builds for this project.

Travis-CI is going to be raising prices on their plans soon, so I'm verifying a few things to inform if we move from monthly-to-annual billing to delay the cost increase (at least for a year):

1. Is Travis-CI still required for this project's CI/build needs?
2. Does the project anticipate being able to move off of Travis-CI at any point, particularly before March 2026?
